Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5
LM9071SX from Texas Instruments, in a TO-263-5. 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 | INPUT VOLTAGE | power_in | Regulator supply input with an operating range of 6V to 26V, absolute maximum -26V to +40V, and 60V positive and -50V negative transient capability, with a 1 µF or larger input capacitor recommended. |
| 2 | RESET OUTPUT | output | Active-low delayed reset flag with an internal 12 kΩ to 80 kΩ pull-up, a maximum sink current of 5 mA, and a low level of at most 0.4V at 1.6 mA sink when VOUT > 3.2V. |
| 3 | GROUND | power_in | Ground reference pin, internally connected to the tab and backside metal of the package. |
| 4 | DELAY CAPACITOR | passive | Connection for the external capacitor (0.1 µF typical) that sets the reset delay time, charged with 10 µA to 30 µA. |
| 5 | OUTPUT VOLTAGE | power_out | Regulated 5V output (4.85V to 5.15V) delivering up to 250 mA, requiring an output capacitor of at least 10 µF (47 µF recommended) with ESR below 3Ω. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
