LN1234B132MR-G

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

LN1234B132MR-G from NATLINEAR, in a SOT-23-5L. 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 Regulator input supply pin. Operating range 1.8 V to 5 V (absolute max +5 V); requires ≥1 μF ceramic bypass capacitor close to the pin. VIN ≥ 2.5 V is required to deliver the full 300 mA output.
2 VSS power_in Device ground / return pin (0 V reference). Connect directly to the ground plane; tie the return sides of CIN and COUT here.
3 CE input Chip-enable / ON-OFF control input. Active-high on the 'B' option (no internal pull-down): VCEH ≥ 1.2 V enables the regulator, VCEL ≤ 0.6 V places the device in shutdown (<0.1 μA). Absolute max VCE = VIN + 0.3 V; input leakage ±0.1 μA.
4 NC unconnected No internal connection. Leave floating or tie to VSS.
5 VOUT power_out Regulated output. Factory-trimmed to 1.3 V for the -132- ordering code with ±2.0% accuracy (±30 mV below 1.5 V), delivering up to 300 mA when VIN ≥ 2.5 V. Requires ≥1 μF ceramic output capacitor for stability; internally current-limited (~60 mA short-circuit).
