LR6205B28M

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

LR6205B28M from LRC, 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 Power input pin; the datasheet specifies an input voltage of 2.0 V to 6.0 V, with absolute maximum rating VSS-0.3 V to VSS+7 V.
2 VSS power_in Ground pin, the reference for the input, output and CE levels.
3 CE input Chip enable input, TTL-logic controlled; for this B-suffix part it is active-high with a built-in pull-down resistor, with CE "High" at least 1.5 V (up to VIN) and CE "Low" at most 0.3 V, and CE = VSS gives a standby current of 0.1 µA.
4 NC unconnected No connection.
5 VOUT power_out Regulated output pin; the 2.8 V output (per the part designator 28) is rated for output current up to 500 mA in the electrical characteristics, with 600 mA absolute maximum and 100 mA typical short-circuit current.
