# LM9076BMAX-3.3

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

LM9076BMAX-3.3 from Texas Instruments, in a SOIC-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 | /RESET | output | Active-low open-collector delayed reset output that needs an external pull-up resistor of 10 kΩ to 200 kΩ and is rated -0.3V to 20V. |
| 2 | CDELAY | passive | Delay capacitor pin charged at 420 nA typical to set the reset delay time, using a low-leakage capacitor, rated -0.3V to VOUT +0.3V. |
| 3 | SHUTDOWN | input | On/Off control input where high switches the output off and low or open switches it on, with operating range 0V to 40V and absolute maximum -15V to +52V. |
| 4 | GND | power_in | Ground pin for the regulator. |
| 5 | VIN | power_in | Unregulated input supply with operating range 5.35V to 40V, requiring a 10 µF capacitor plus a 0.1 µF ceramic capacitor close to the pin. |
| 6 | N/C | unconnected | No internal connection. |
| 7 | N/C | unconnected | No internal connection. |
| 8 | VOUT | power_out | Regulated 3.3V output rated for up to 150 mA, requiring a minimum 10 µF output capacitor within the stated ESR limits. |
