GM1200ACPZ from GONGMOSEMI, in a DFN-10(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IN	power_in	Regulator supply input. Pins 1 and 2 are tied together internally to IN. Requires a typical 4.7µF bypass capacitor; large load transients need more input capacitance to prevent supply droop. Input range 2.6V to 20V.
2	IN	power_in	Regulator supply input, paralleled with pin 1. Requires 4.7µF typical bypass capacitor.
3	EN/UV	input	Enable / undervoltage-lockout input. Pulling EN/UV low (<1µA quiescent) places the device in shutdown. A resistor divider between IN, EN/UV, and GND sets a programmable UVLO threshold; rising threshold typically 1.07V with 100mV hysteresis. Tie to IN if not used; do not leave floating.
4	PG	output	Power-good open-drain output. Asserts high (Hi-Z) when PGFB > 302mV, indicating output regulation is within spec. Leave floating if power-good indication is not needed.
5	ILIM	passive	Programmable current-limit input. A resistor from ILIM to GND (Kelvin-connected to the GM1200 GND pin) sets the current limit; programming scale factor is typically 128mA·kΩ. May also serve as a 0V-to-300mV current-monitor output. Tie to GND if programmable limit is not needed.
6	PGFB	input	Power-good feedback input. PG asserts when PGFB rises above 302mV, with 60mV falling hysteresis. External divider between OUT, PGFB, and GND programs the power-good threshold: VPG_thr = 0.305V·(1 + RPG2/RPG1). PGFB also enables the fast-start-up circuit. Tie to IN if power-good and fast-start are not needed.
7	SET	input	Output-voltage setpoint. Inverting input of the error amplifier. Sources a precise 100µA reference current through an external RSET between SET and GND: VOUT = ISET·RSET (adjustable 1.5V to 15V). Adding a capacitor from SET to GND reduces output noise, PSRR ripple, and improves transient response at the cost of longer startup. Use Kelvin connection of the RSET ground to the load return for best load regulation.
8	GND	power_in	Device ground. The DFN exposed pad (pin 11) must be soldered to the PCB GND plane and connected directly to this pin for proper electrical and thermal performance.
9	OUTS	input	Output sense; non-inverting input of the error amplifier. For best transient response and load regulation, Kelvin-connect OUTS directly to the output capacitor and the load. Route the input/output capacitor GND returns near this pin.
10	OUT	power_out	Regulated output; supplies load current up to 200mA. Requires a minimum 4.7µF ceramic output capacitor with ESR < 50mΩ and ESL < 2nH for stability. Larger load transients require more output capacitance to limit peak deviation.
11	GND (EPAD)	power_in	Exposed thermal pad on the DFN package bottom. Must be soldered directly to a PCB ground plane for proper electrical and thermal performance and connected to pin 8.
