Description
The G5M2163 series of positive, linear regulators feature low quiescent current (30ꢀA typ.) with low dropout
voltage, making them ideal for battery applications.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under
the “Worst” of operating conditions.
In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground.
The G5M2163 is stable with an output capacitance of 2.2ꢀF or greater.

Detailed Description
The G5M2163 series of COMS regulators contain a PMOS pass transistor, voltage reference, error amplifier,
over-current protection, and thermal shutdown.
The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal
protection circuits. During normal operation, the error amplifier compares the output voltage to a precision
reference. Over-current and Thermal shutdown circuits become active when the junction temperature exceeds
150к, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal
operation is restored when the junction temperature drops below 120к.
The G5M2163 switches from voltage mode to current mode when the load exceeds the rated output current.
This prevents over-stress. The G5M2163 also incorporates current fold-back to reduce power dissipation when
the output is short circuited. This feature becomes active when the output drops below 0.8 volts, and reduces
the current flow by 65%. Full current is restored when the voltage exceeds 0.8 volts.
External Capacitors
The G5M2163 is stable with an output capacitance to ground of 2.2ꢀF or greater. Ceramic capacitors have the
lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the
highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are
comparatively expensive. One option is to parallel a 0.1ꢀF ceramic capacitor with a 10ꢀF Aluminum Electrolytic.
The benefit is low ESR, high capacitance, and low overall cost.
A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should
be at least 0.1ꢀF to have a beneficial effect.
A third capacitor can be connected between the BY-PASS pin and GND. This capacitor can be a low cost
Polyester Film variety between the value of 0.001~0.01ꢀF. A large capacitor improves the AC ripple rejection,
but also makes the output come up slowly. This “Soft” turn-on is desirable in some applications to limit turn-on
surges.
All capacitors should be placed in close proximity to the pins. A “Quiet” ground termination is desirable. This
can be achieved with a “Star” connection.
Enable
The Enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shuts off, and all
internal circuits are powered down. In this state, the quiescent current is less than 1ꢀA. This pin behaves much
like an electronic switch.
