LN1152B122MR-G

NATLINEAR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LN1152B122MR-G from NATLINEAR, in a SOT-23-5L. 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 supply pin, operating range 2.0 V to 7 V, with absolute maximum rating VSS−0.3 V to VSS+8 V.
2 VSS power_in Ground pin, the reference for all absolute maximum ratings (VIN, VOUT and CE are specified relative to VSS).
3 CE input Enable input; the B-option of this MPN is active-high with a built-in pull-down resistor, minimum high level 1.6 V, maximum low level 0.5 V, and absolute maximum VSS−0.3 V to VIN+0.3 V.
4 NC unconnected No connection (listed as 空, empty, in the datasheet pin table).
5 VOUT power_out Regulated output pin, absolute maximum VSS−0.3 V to VIN+0.3 V, with output current up to 500 mA when VIN ≥ VOUT+1 V.
