SSP9193-18M5R

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SSP9193-18M5R from Shanghai Siproin Microelectronics, in a SOT-23-5. 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 voltage. Recommended operating range 2.5V to 5.5V. Bypass to GND with a 1uF X7R ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference. Return path for input/output capacitors and reference for the EN threshold.
3 EN input Chip Enable, active high (VIH >= 1.2V enables, VIL <= 0.4V shuts down). High-impedance input; use a 100kOhm pull-down to GND if the driving signal may float. Standby current in shutdown is <0.01uA (typ).
4 BP passive Reference noise bypass. May be left floating; for lowest output noise (~27uVrms), connect a 22nF ceramic capacitor between BP and GND.
5 VOUT power_out Regulated output voltage (1.8V for the -18 option), ±2% tolerance, up to 300mA continuous. Requires a >=1uF X7R ceramic capacitor to GND placed close to the pin for stability.
