LN1134A302MR-G

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

LN1134A302MR-G from NATLINEAR, in a SOT-23-5. 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 Voltage input; absolute maximum is VSS-0.3 V to VSS+8 V, and the stated operating input range is 2.0 V to 7 V, with at least VOUT+1 V needed for the 300 mA output current rating.
2 VSS power_in Ground pin; all voltage limits on VIN, VOUT and CE are referenced to VSS.
3 CE input Enable pin, active high for the LN1134A version (internal pull-down); its absolute range is VSS-0.3 V to VIN+0.3 V, with a minimum high level of 1.6 V and a maximum low level of 0.25 V.
4 NC unconnected No connection; leave floating.
5 VOUT power_out Regulated output; absolute range is VSS-0.3 V to VIN+0.3 V, and output current is up to 300 mA when VIN is at least VOUT+1 V, with set output accuracy of ±2.0%.
