These regulators are protected against over current conditions and include thermal shutdown protection. The GM1117S has a composite PNP-NPN output transistor and require an output capacitor for stability. A detailed procedure for selecting this capacitor follows. Adjustable Operation The GM1117S has an output voltage range for 1.25V to 5.5V. An external resistor divider sets the output voltage as show in Figure 1. The regulator maintains a fixed 1.25V (typical) reference between the output pin and the adjust pin. A resistor divider network R1 and R1 causes a fixed current to follow to ground. This current creates a voltage across R2 that adds to the 1.25V across R1 and sets the overall output voltage. The adjust pin current (typically 50µA) also flows through R2 and adds a small error that should be taken into account if precise adjustment of VOUT is necessary. GM1117S VIN VIN C1 VOUT Adj VOUT VREF R1 C2 IADJ VOUT =1.25V ( 1+ R2 R1 CADJ R2 ) Figure 1. Resistor Divider Scheme The term IADJ X R2 represents the error added by the adjust pin current. R1 is chosen such that the minimum load current is at least 2mA. R1 and R2 should be the same type, e.g., metal film for best tracking over temperature. While not require, a bypass capacitor from the adjust pin to ground will improve ripple rejection and transient response. A 0.1µF tantalum capacitor is recommended. GM1117SV2.03 Stability Considerations 10 The output compensation capacitor helps to determine three feature characteristics of a linear regulator's performance: start-up delay, load transient response, and loop stability. The capacitance and type is based on cost, availability, size and temperature constraints. A tantalum or aluminum electrolytic capacitor is preferred, as a film or ceramic capacitor with almost zero ESR can cause instability. An aluminum electrolytic capacitor is the least expensive type, but when the circuit operates at low temperatures, both the capacitance and ESR will vary widely. For optimum performance over the full operating temperature range, a tantalum capacitor is best. A 22µF tantalum capacitor will work fine in most applications, but with high current regulators such as the GM1117S higher capacitance values will improve the transient response and stability. Most applications for the GM1117S involve large changes in load current, so the output capacitor must supply instantaneous load current. The ESR of the output capacitor causes an immediate drop in output voltage given by: △V = △I X ESR In microprocessor applications, an output capacitor network of several tantalum and ceramic capacitors in parallel is commonly used. This reduces overall ESR and minimizes the instantaneous output voltage drop under transient load conditions. The output capacitor network should be placed as close to the load as possible. GM1117S 1A LOW DROPOUT PRECISION VOLTAGE REGULATOR Heatsink Requirements When an integrated circuit operates with an appreciable current, its junction temperature is elevated. It is important to consider its thermal limits in order to achieve acceptable performance and reliability. This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating environment. The heat generated at the device junction flows through the die to the die attach pad, through the lead frame to the surrounding case material, to the printed circuit board, and eventually to the ambient environment. Below is a list of variables that may affect the thermal resistance and in turn the need to a heatsink. ΘJC, Junction to Case Thermal Resistance ΘCA, Case to Ambient Thermal Resistance 1. Lead Frame Size & Material 1. Mounting Pad Size, Material & Location 2. Number of conducting Pins 2. Placement of Mounting Pad 3. Die Size 3. PCB Size & Material 4. Die Attach Material 4. Traces Length & Width 5. Molding Compound Size & Material 5. Adjacent Heat Source 6. Volume of Air 7. Ambient Temperature 8. Shape of Mounting Pad The GM1117S regulators have internal thermal shutdown to protect the device from over heating. Under all possible operating conditions, the junction temperature of the GM1117S must be within in the range of 0°C to 125°C. A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application. To determine if a heatsink is needed, the power dissipated y the regulator, PD, must be calculated according to the circuit below: IIN VIN GM1117S VIN VOUT LOAD Gnd VOUT IIN = IL + IG PD = (VIN – VOUT) X IL + VIN X IG IL IG The next parameter which must be calculated is the maximum allowable temperature rise, TR(max): TR(max) = TJ(max) – TA(max) Using the calculated values for TR(max) and PD the maximum allowable value for the junction-to-ambient thermal resistance (θJA) can be calculated: ΘJA(max) = TR(max) X PD If the maximum allowable value for ΘJA is found to be > 136°C/W for SOT223 packages or > 79°C/W for TO220 package or > 92°C/W for TO252 package, no heat sink is needed since the package alone will dissipate enough heat to satisfy these requirements. If the calculated value for ΘJA falls below these limits, a heat sink is required. GM1117SV2.03 Where TJ(max) is the maximum allowable junction temperature (125°C) and TA(max) is the maximum ambient temperature which will be encountered in the application. 11 GM1117S 1A LOW DROPOUT PRECISION VOLTAGE REGULATOR As a design aid, the table below shows the value of the ΘJA of SOT-223 and TO-252 for different heat sink area.
