LP3892 www.ti.com SNVS236D – SEPTEMBER 2003 – REVISED APRIL 2013 LP3892 1.5A Fast-Response Ultra Low Dropout Linear Regulators Check for Samples: LP3892 FEATURES DESCRIPTION • The LP3892 is a high current, fast response regulator which can maintain output voltage regulation with minimum input to output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages: Vbias provides voltage to drive the gate of the N-MOS power transistor, while Vin is the input voltage which supplies power to the load. The use of an external bias rail allows the part to operate from ultra low Vin voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. 1 2 • • • • • • • Ultra Low Dropout Voltage (140 mV at 1.5A typ) Low Ground Pin Current Load Regulation of 0.04%/A 60 nA Typical Quiescent Current in Shutdown 1.5% Output Accuracy (25°C) TO-220, DDPAK/TO-263 and SO PowerPAD-8 Packages Over Temperature/Over Current Protection −40°C to +125°C Junction Temperature Range APPLICATIONS • • • • • • • DSP Power Supplies Server Core and I/O Supplies PC Add-in-Cards Local Regulators in Set-Top Boxes Microcontroller Power Supplies High Efficiency Power Supplies SMPS Post-Regulators The fast transient response of these devices makes them suitable for use in powering DSP, Microcontroller Core voltages and Switch Mode Power Supply post regulators.

Operating ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For specifications, see Electrical Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions. The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin. The machine model is a 220 pF capacitor discharged directly into each pin. The machine model ESD rating of pin 5 is 100V. At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values. θJ-A for TO-220 devices is 65°C/W if no heatsink is used. If the TO-220 device is attached to a heatsink, a θJ-S value of 4°C/W can be assumed. θJ-A for DDPAK/TO-263 devices is approximately 40°C/W if soldered down to a copper plane which is at least 1.5 square inches in area. θJ-A value for typical SO PowerPAD-8 PC board mounting is 166°C/W. If power dissipation causes the junction temperature to exceed specified limits, the device will go into thermal shutdown.

Typical numbers represent the most likely parametric norm for 25°C operation. If used in a dual-supply system where the regulator load is returned to a negative supply, the output pin must be diode clamped to ground. Output voltage line regulation is defined as the change in output voltage from nominal value resulting from a change in input voltage. Output voltage load regulation is defined as the change in output voltage from nominal value as the load current increases from no load to full load. Dropout voltage is defined as the minimum input to output differential required to maintain the output with 2% of nominal value. The SO PowerPAD-8 package devices have a slightly higher dropout voltage due to increased band wire resistance.

OUTPUT CAPACITOR At least 10µF of output capacitance is required for stability (the amount of capacitance can be increased without limit). The output capacitor must be located less than 1 cm from the output pin of the IC and returned to a clean analog ground. The ESR (equivalent series resistance) of the output capacitor must be within the "stable" range as shown in Figure 19 over the full operating temperature range for stable operation. 10 COUT ESR (:) 1.0 COUT > 10 PF STABLE REGION 0.1 .01 .001 0 1 LOAD CURRENT (A) 2 Figure 19. Minimum ESR vs Output Load Current Tantalum capacitors are recommended for the output as their ESR is ideally suited to the part's requirements and the ESR is very stable over temperature. Aluminum electrolytics are not recommended because their ESR increases very rapidly at temperatures below 10°C. Aluminum caps can only be used in applications where lower temperature operation is not required. A second problem with Al caps is that many have ESR's which are only specified at low frequencies. The typical loop bandwidth of a linear regulator is a few hundred kHz to several MHz. If an Al cap is used for the output cap, it must be one whose ESR is specified at a frequency of 100 kHz or more. Because the ESR of ceramic capacitors is only a few milliohms, they are not suitable for use as output capacitors on LP389X devices. The regulator output can tolerate ceramic capacitance totaling up to 15% of the amount of Tantalum capacitance connected from the output to ground. INPUT CAPACITOR The input capacitor must be at least 10 µF, but can be increased without limit. It's purpose is to provide a low source impedance for the regulator input. Ceramic capacitors work best for this, but Tantalums are also very good. There is no ESR limitation on the input capacitor (the lower, the better). Aluminum electrolytics can be used, but their ESR increase very quickly at cold temperatures. They are not recommended for any application where temperatures go below about 10°C. BIAS CAPACITOR The 0.1µF capacitor on the bias line can be any good quality capacitor (ceramic is recommended). BIAS VOLTAGE The bias voltage is an external voltage rail required to get gate drive for the N-FET pass transistor. Bias voltage must be in the range of 4.5 - 6V to assure proper operation of the part. UNDER VOLTAGE LOCKOUT The bias voltage is monitored by a circuit which prevents the regulator output from turning on if the bias voltage is below approximately 4V. 8 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LP3892 LP3892 www.ti.com SNVS236D – SEPTEMBER 2003 – REVISED APRIL 2013 SHUTDOWN OPERATION Pulling down the shutdown (S/D) pin will turn-off the regulator. Pin S/D must be actively terminated through a pull-up resistor (10 kΩ to 100 kΩ) for a proper operation. If this pin is driven from a source that actively pulls high and low (such as a CMOS rail to rail comparator), the pull-up resistor is not required. This pin must be tied to Vin if not used. POWER DISSIPATION/HEATSINKING A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application. Under all possible conditions, the junction temperature must be within the range specified under operating conditions. The total power dissipation of the device is given by: PD = (VIN−VOUT)IOUT+ (VIN)IGND (1) where IGND is the operating ground current of the device. The maximum allowable temperature rise (TRmax) depends on the maximum ambient temperature (TAmax) of the application, and the maximum allowable junction temperature (TJmax): TRmax = TJmax− TAmax (2) The maximum allowable value for junction to ambient Thermal Resistance, θJA, can be calculated using the formula: θJA = TRmax / PD (3) These parts are available in TO-220 and DDPAK/TO-263 packages. The thermal resistance depends on amount of copper area or heat sink, and on air flow. If the maximum allowable value of θJA calculated above is ≥ 60 °C/W for TO-220 package and ≥ 60 °C/W for DDPAK/TO-263 package no heatsink is needed since the package can dissipate enough heat to satisfy these requirements. If the value for allowable θJA falls below these limits, a heat sink is required. HEATSINKING TO-220 PACKAGE The thermal resistance of a TO-220 package can be reduced by attaching it to a heat sink or a copper plane on a PC board. If a copper plane is to be used, the values of θJA will be same as shown in next section for DDPAK/TO-263 package. The heatsink to be used in the application should have a heatsink to ambient thermal resistance, θHA≤ θJA − θCH − θJC. In this equation, θCH is the thermal resistance from the case to the surface of the heat sink and θJC is the thermal resistance from the junction to the surface of the case. θJC is about 3°C/W for a TO-220 package. The value for θCH depends on method of attachment, insulator, etc. θCH varies between 1.5°C/W to 2.5°C/W. If the exact value is unknown, 2°C/W can be assumed. HEATSINKING DDPAK/TO-263 PACKAGE The DDPAK/TO-263 package uses the copper plane on the PCB as a heatsink. The tab of these packages are soldered to the copper plane for heat sinking. The graph below shows a curve for the θJA of DDPAK/TO-263 package for different copper area sizes, using a typical PCB with 1 ounce copper and no solder mask over the copper area for heat sinking. Figure 20. θJA vs Copper (1 Ounce) Area for DDPAK/TO-263 Package Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LP3892 9 LP3892 SNVS236D – SEPTEMBER 2003 – REVISED APRIL 2013 www.ti.com As shown in the graph below, increasing the copper area beyond 1 square inch produces very little improvement. The minimum value for θJA for the DDPAK/TO-263 package mounted to a PCB is 32°C/W. Figure 22 shows the maximum allowable power dissipation for DDPAK/TO-263 packages for different ambient temperatures, assuming θJA is 35°C/W and the maximum junction temperature is 125°C. Figure 21. Maximum Power Dissipation vs Ambient Temperature for DDPAK/TO-263 Package HEATSINKING SO PowerPAD PACKAGE Heatsinking for the SO PowerPAD-8 package is accomplished by allowing heat to flow through the ground slug on the bottom of the package into the copper on the PC board. The heat slug must be soldered down to a copper plane to get good heat transfer. It can also be connected through vias to internal copper planes. Since the heat slug is at ground potential, traces must not be routed under it which are not at ground potential. Under all possible conditions, the junction temperature must be within the range specified under operating conditions.
