LR6232A33M

LRC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

LR6232A33M from LRC, in a SOT-23-3. 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 VIN power_in Power input pin. Accepts 1.8-8 V (absolute max 9 V). Bypass with a 1 µF ceramic capacitor to VSS close to the pin; add ~3 Ω series resistance with X5R ceramics to suppress start-up transients.
2 VSS power_in Device ground / negative supply reference. All voltages are referenced to this network ground terminal.
3 CE input Chip Enable input. Drive high (V_CE(H) ≥ 1.5 V, up to VIN) to enable the regulator; drive low (V_CE(L) ≤ 0.3 V) to shut down (standby current ≤ 0.1 µA). Tie to VIN if enable control is not required.
4 NC unconnected No internal connection. Leave floating or tie to VSS at the designer's discretion.
5 VOUT power_out Regulated output pin. Delivers a fixed 3.3 V (A33 option) at up to 300 mA continuous, with 110 mV typical dropout at 100 mA. Requires a 1 µF output capacitor (tantalum or ceramic) to VSS close to the pin for loop stability.
