GM12043AKCZ-R7

GONGMOSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

GM12043AKCZ-R7 from GONGMOSEMI, in a SOT-223-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SHDN input Shutdown pin: pull high to enable the device and low to disable it, with SHDN_IH 0.79 V to 1.1 V and SHDN_IL 0.49 V to 0.75 V; if enable control is not needed, it must be connected to IN.
2 IN power_in Input pin with an absolute maximum rating of -0.3 V to +22 V and an operating input range of 1.9 V to 20 V, requiring a 10 µF or larger ceramic capacitor (7 µF or larger) placed as close to the pin as possible.
3 GND power_in Ground pin, listed together with pin 6 as GND for the GM12043AKCZ-R7.
4 OUT power_out Regulated output with an absolute maximum rating of -0.3 V to +22 V, requiring a 10 µF or larger ceramic capacitor to GND placed as close to the pin as possible for stability.
5 SENSE/ADJ input Feedback pin to the error amplifier: SENSE for fixed-output versions, and ADJ at 0.9 V, 1.0 V, 1.1 V or 1.21 V relative to ground for adjustable output up to 20 V, with an absolute maximum rating of -0.3 V to +6 V.
6 GND power_in Ground pin, listed together with pin 3 as GND for the GM12043AKCZ-R7; the datasheet gives no further function for it.
