L99VR01STR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SO-8

L99VR01STR from STMicroelectronics, in a SO-8. 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 VS power_in Supply voltage input (DC absolute maximum -0.3 V to 28 V, with 40 V single-pulse load dump); block directly to ground with a ceramic capacitor of at least 4.7 µF and a 100 nF capacitor placed as close as possible to the pin.
2 SEL1 input Output voltage selector input, with the input voltage limited to -0.3 V to VS + 0.3 V; together with SEL2 and SEL3 it selects the output voltage from 0.8 V to 5 V.
3 SEL2 input Output voltage selector input, with the input voltage limited to -0.3 V to VS + 0.3 V; together with SEL1 and SEL3 it selects the output voltage from 0.8 V to 5 V.
4 SEL3 input Output voltage selector input, with the input voltage limited to -0.3 V to VS + 0.3 V; together with SEL1 and SEL2 it selects the output voltage from 0.8 V to 5 V.
5 EN input Enable input (limited to -0.3 V to VS + 0.3 V): high enables the regulator, watchdog and reset, while low shuts them down and turns on the fast output discharge; connect to VS to keep the device always enabled.
6 GND power_in Ground reference for the device.
7 RST output Reset output, pulled down when the output voltage goes below Vo_th; limited to -0.3 V to VO + 0.3 V and can be left floating if not used.
8 VO power_out Voltage regulator output (200 mA capability); block to ground with a capacitor of at least 3.3 µF for regulator stability.
