These capacitors must be correctly selected for proper performance. Input Capacitor A ceramic input capacitor of at least 10 µF is required. For general usage across all load currents and operating conditions, a 10 µF ceramic input capacitor will provide satisfactory performance. Output Capacitor A ceramic capacitor with a minimum value of 10 µF is required at the output pin for loop stability. It must be located less than 1 cm from the device and connected directly to the output and ground pin using traces which have no other currents flowing through them. As long as the minimum of 10 µF ceramic is met, there is no limitation on any additional capacitance. X7R and X5R dielectric ceramic capacitors are strongly recommended, as they typically maintain a capacitance range within ±20% of nominal over full operating ratings of temperature and voltage. Of course, they are typically larger and more costly than Z5U/Y5U types for a given voltage and capacitance. Z5U and Y5V dielectric ceramics are not recommended as the capacitance will drop severely with applied voltage. A typical Z5U or Y5V capacitor can lose 60% of its rated capacitance with half of the rated voltage applied to it. The Z5U and Y5V also exhibit a severe temperature effect, losing more than 50% of nominal capacitance at high and low limits of the temperature range. Application Information REVERSE VOLTAGE A reverse voltage condition will exist when the voltage at the output pin is higher than the voltage at the input pin. Typically this will happen when VIN is abruptly taken low and COUT continues to hold a sufficient charge such that the input to output voltage becomes reversed. A less common condition is when an alternate voltage source is connected to the output. There are two possible paths for current to flow from the output pin back to the input during a reverse voltage condition. While VIN is high enough to keep the control circuity alive, and the Enable pin is above the VEN(ON) threshold, the control circuitry will attempt to regulate the output voltage. Since the input voltage is less than the programmed output voltage, the control circuit will drive the gate of the pass element to the full on condition when the output voltage begins to fall. In this condition, reverse current will flow from the output pin to the input pin, limited only by the RDS(ON) of the pass element and the output to input voltage differential. Discharging an output capacitor up to 1000 µF in this manner will not damage the device as the current will rapidly decay. However, continuous reverse current should be avoided. When the Enable is low this condition will be prevented. The internal PFET pass element in the LP38513-ADJ has an inherent parasitic diode. During normal operation, the input voltage is higher than the output voltage and the parasitic diode is reverse biased. However, if the output voltage to input voltage differential is more than 500 mV (typical) the parasitic diode becomes forward biased and current flows from the output pin to the input pin through the diode. The current in the parasitic diode should be limited to less than 1A continuous and 5A peak. If used in a dual-supply system where the regulator output load is returned to a negative supply, the output pin must be diode clamped to ground. A Schottky diode is recommended for this protective clamp. SHORT-CIRCUIT PROTECTION The LP38513-ADJ is short circuit protected, and in the event of a peak over-current condition the short-circuit control loop will rapidly drive the output PMOS pass element off. Once the power pass element shuts down, the control loop will rapidly cycle the output on and off until the average power dissipation causes the thermal shutdown circuit to respond to servo the on/off cycling to a lower frequency. Please refer to the POWER DISSIPATION/HEAT-SINKING section for power dissipation calculations.

The output voltage is given by the formula: VOUT = VADJ x (1 + (R1/R2)) (1) The resistors used for R1 and R2 should be high quality, tight tolerance, and with matching temperature coefficients. It is important to remember that, although the value of VADJ is specified, the final value of VOUT is not. The use of low quality resistors for R1 and R2 can easily produce a VOUT value that is unacceptable. It is recommended that the values selected for R1 and R2 are such that the parallel value is less than 1.00 kΩ. This is to reduce the possibility of any internal parasitic capacitances on the ADJ pin from creating an undesirable phase shift that may interfere with device stability. ( (R1 x R2) / (R1 + R2) ) ≤ 1.00 kΩ (2) FEED FORWARD CAPACITOR, CFF When using a ceramic capacitor for COUT, the typical ESR value will be too small to provide any meaningful positive phase compensation, FZ, to offset the internal negative phase shifts in the gain loop. FZ = 1 / (2 x π x COUT x ESR) (3) A capacitor placed across the gain resistor R1 will provide additional phase margin to improve load transient response of the device. This capacitor, CFF, in parallel with R1, will form a zero in the loop response given by the formula: FZ = 1 / (2 x π x CFF x R1) (4) For optimum load transient response select CFF so the zero frequency, FZ, falls between 20 kHz and 40 kHz. CFF = 1 / (2 x π x R1 x FZ) (5) The phase lead provided by CFF diminishes as the DC gain approaches unity, or VOUT approaches VADJ. This is because CFF also forms a pole with a frequency of: FP = 1 / (2 x π x CFF x (R1 || R2) ) (6) It's important to note that at higher output voltages, where R1 is much larger than R2, the pole and zero are far apart in frequency. At lower output voltages the frequency of the pole and the zero mover closer together. The phase lead provided from CFF diminishes quickly as the output voltage is reduced, and has no effect when VOUT = VADJ. For this reason, relying on this compensation technique alone is adequate only for higher output voltages. Table 1 lists some suggested, best fit, standard ±1% resistor values for R1 and R2, and a standard ±10% capacitor values for CFF, for a range of VOUT values. Other values of R1, R2, and CFF are available that will give similar results. 10 Submit Documentation Feedback Copyright © 2009–2013, Texas Instruments Incorporated Product Folder Links: LP38513-ADJ LP38513-ADJ www.ti.com SNVS514C – JANUARY 2009 – REVISED APRIL 2013 Table 1.

ENABLE OPERATION The Enable ON threshold is typically 1.2V, and the OFF threshold is typically 1.0V. To ensure reliable operation the Enable pin voltage must rise above the maximum VEN(ON) threshold and must fall below the minimum VEN(OFF) threshold. The Enable threshold has typically 200mV of hysteresis to improve noise immunity. The Enable pin (EN) has no internal pull-up or pull-down to establish a default condition and, as a result, this pin must be terminated either actively or passively. If the Enable pin is driven from a single ended device (such as the collector of a discrete transistor) a pull-up resistor to VIN, or a pull-down resistor to ground, will be required for proper operation. A 1 kΩ to 100 kΩ resistor can be used as the pull-up or pull-down resistor to establish default condition for the EN pin. The resistor value selected should be appropriate to swamp out any leakage in the external single ended device, as well as any stray capacitance. If the Enable pin is driven from a source that actively pulls high and low (such as a CMOS rail to rail comparator output), the pull-up, or pull-down, resistor is not required. If the application does not require the Enable function, the pin should be connected directly to the adjacent VIN pin. POWER DISSIPATION/HEAT-SINKING A heat-sink may be required depending on the maximum power dissipation (PD(MAX)), maximum ambient temperature (TA(MAX))of the application, and the thermal resistance (θJA) of the package. Under all possible conditions, the junction temperature (TJ) must be within the range specified in the Operating Ratings. The total power dissipation of the device is given by: PD = ( (VIN−VOUT) x IOUT) + ((VIN) x IGND) (7) where IGND is the operating ground current of the device (specified under Electrical Characteristics). The maximum allowable junction temperature rise (ΔTJ) depends on the maximum expected ambient temperature (TA(MAX)) of the application, and the maximum allowable junction temperature (TJ(MAX)): ΔTJ = TJ(MAX) − TA(MAX) (8) The maximum allowable value for junction to ambient Thermal Resistance, θJA, can be calculated using the formula: θJA = ΔTJ / PD(MAX) (9) Submit Documentation Feedback Copyright © 2009–2013, Texas Instruments Incorporated Product Folder Links: LP38513-ADJ 11 LP38513-ADJ SNVS514C – JANUARY 2009 – REVISED APRIL 2013 www.ti.com LP38513-ADJ is available in the TO-263 THIN surface mount package. For a comparison of the TO-263 THIN package to the standard TO-263 package see Application Note AN-1797 TO-263 THIN Package SNVA328. The thermal resistance depends on amount of copper area, or heat sink, and on air flow. See Application Note AN1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages SNVA183 for guidelines. Heat-Sinking the TO-263 THIN Package The DAP of the TO-263 THIN package is soldered to the copper plane for heat sinking. The TO-263 THIN package has a θJA rating of 67°C/W, and a θJC rating of 2°C/W. The θJA rating of 67°C/W includes the device DAP soldered to an area of 0.055 square inches (0.22 in x 0.25 in) of 1 ounce copper on a two sided PCB, with no airflow. See JEDEC standard EIA/JESD51-3 for more information. Figure 19 shows a curve for the θJA of TO-263 THIN package for different thermal via counts under the exposed DAP, using a four layer PCB for heat sinking. The thermal vias connect the copper area directly under the exposed DAP to the first internal copper plane only. See JEDEC standards EIA/JESD51-5 and EIA/JESD51-7 for more information.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
