SGM2053-ADJXN6G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-6

SGM2053-ADJXN6G from SGMICRO, in a SOT-23-6. 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 VIN power_in Input voltage supply pin, operating from 1.5V to 5.5V; the datasheet recommends a 2.2μF or larger ceramic capacitor from VIN to ground.
2 GND power_in Ground pin.
3 EN input Enable pin: drive high (above 0.7V) to turn the regulator on and low (below 0.3V) to turn it off; an internal 0.03μA pull-down holds the device off when EN is floated.
4 BP passive Reference-noise bypass pin; an external capacitor CBP (22nF in the typical application) reduces output noise to a very low level.
5 ADJ input Feedback input for the adjustable version (NC on fixed-output versions); connect to an external resistor divider to set VOUT from 0.8V to 5.0V, with the resistors placed as close to this pin as possible.
6 VOUT power_out Regulator output pin; the datasheet recommends an effective output capacitance of 1μF to 10μF placed as close as possible to this pin.
