Description
GM1117S
1A LOW DROPOUT
PRECISION VOLTAGE REGULAT OR
Features
The GM1117S is a positive low dropout
regulator and is available in an adjustable
version and fixed output voltage from 1.5V to
5.0V. All internal circuitry is designed to
operate down to 800mV input to output
differential and the dropout voltage is fully
specified as a function of load current. On chip
trimming adjusts the reference/output voltage
to within ± 1%. Current limit is also trimmed in
order to minimize the stress on both the
regulator and the power source circuitry under
overloaded conditions.

Application Notes
PRECISION VOLT AGE REGULATOR
1A LOW DROPOUT
GM1117S linear regulators provide fixed and adjustable output voltage at current up to 1.0A. 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 V
is necessary.

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.
Stability Considerations
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:
2.03
△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.

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.

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, P

The next parameter which must be calculated is the maximum allowable temperature rise, T

Where T
(max) is the maximum allowable junction temperature (125°C) and TA(max) is the maximum
J
(max):
R
ambient temperature which will be encountered in the application.
Using the calculated values for T
thermal resistance (θ

D
D the maximum allowable
value for the junction-to-ambient
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 Θ
JA
falls
below these limits, a heat sink is required.
