GM1200ARMZ-R7 from GONGMOSEMI, in a MSOP-10. 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 (paralleled with pin 2). Requires a typical 4.7µF bypass capacitor to GND; applications with large load transients may need more input capacitance to prevent input supply droop. Operating range 2.6V to 20V. |
| 2 | IN | power_in | Regulator supply input (paralleled with pin 1). Tie both IN pins together and bypass with 4.7µF minimum ceramic to GND. Operating range 2.6V to 20V. |
| 3 | EN/UV | input | Enable / undervoltage lockout input. Pulling EN/UV below its threshold puts the part into shutdown (Iq < 1µA and output disconnected). A resistor divider from IN to EN/UV to GND programs a user UVLO with 1.07V rising threshold and 100mV hysteresis. Tie to IN if unused; do not float. Absolute max −0.3V to +22V. |
| 4 | PG | output | Power-good open-drain output. Pulled low when PGFB is below 302mV; goes high-Z (pull-up to logic supply required) when PGFB is above the threshold. Leave floating if power-good indication is not needed. VOL = 16mV @ 100µA; leakage 0.5µA max at 20V. |
| 5 | ILIM | bidirectional | Programmable current limit / current monitor. A resistor from ILIM to GND programs the output current limit (scaling factor ≈128 mA·kΩ; e.g. 649Ω → ~197mA). Also outputs a 0-300mV signal proportional to load current for monitoring. Tie to GND if not used. Absolute max −0.3V to +1V. |
| 6 | PGFB | input | Power-good feedback input. A resistor divider from OUT to PGFB to GND sets the power-good rising threshold: VPG_RISE = 0.305V × (1 + RPG2/RPG1) with 43mV hysteresis. PGFB also enables the fast-start circuitry. Tie to IN if power-good/fast-start not used. Input bias 3nA typical. |
| 7 | SET | input | Voltage-set / error-amplifier inverting input. A precision 100µA reference current flows out of SET into an external resistor to GND, so VOUT = ISET × RSET (1.5V to 15V range). Add a capacitor across RSET (typ. 4.7µF) to reduce output noise and improve PSRR at the cost of start-up time. Use Kelvin connection of the SET resistor ground to load ground. Absolute max −0.3V to +16V; SET pin current ±10mA max. |
| 8 | GND | power_in | Ground. Tie the exposed die pad (pin 11 on DFN) directly to this GND pin on the PCB for correct electrical and thermal performance. |
| 9 | OUTS | input | Output sense - non-inverting input of the error amplifier. Kelvin-connect OUTS to the load side of OUT for best transient response and load regulation. The output and SET capacitors (and their GND returns) must be routed very close together. OUTS is intended to be tied directly to OUT. |
| 10 | OUT | power_out | Regulated output (0 to 200mA). Requires a minimum 4.7µF low-ESR ceramic output capacitor (ESR < 50mΩ, ESL < 2nH) for stability. Larger COUT reduces transient droop under fast load steps. Absolute max −0.3V to +16V. |
