BD4269EFJ-CE2

ROHM Semicon · Linear Voltage Regulators (LDO) · ESOP-8

BD4269EFJ-CE2 from ROHM Semicon, in a ESOP-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 VCC power_in Supply voltage input for the regulator.
2 SI input Sense input for the input voltage reset; if not needed, connect to VO.
3 RADJ input Threshold adjust for the power on and under-voltage reset; if not needed, connect to GND.
4 CT passive Delay pin for the power on and under-voltage reset; connect a capacitor to GND to set the delay time.
5 GND power_in Ground reference for the device.
6 RO output Power on and under-voltage reset output; open-collector, internally pulled up to VO via a 24 kΩ resistor, keep open if not needed.
7 SO output Input voltage reset output; open-collector, internally pulled up to VO via a 24 kΩ resistor, keep open if not needed.
8 VO power_out 5 V regulated output.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
