Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-7
LP38852S-ADJ from Texas Instruments, in a TO-263-7. 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 | SS | output | Soft-start capacitor connection used to control the rise time of VOUT at turn-on. |
| 2 | EN | input | Device enable: High = On, Low = Off; the VEN voltage range is 0 V to VBIAS. |
| 3 | IN | input | Unregulated voltage input; VIN cannot exceed either VBIAS or 4.5 V, whichever is lower. |
| 4 | GND | power_in | Ground. |
| 5 | ADJ | output | Feedback connection to set the output voltage, adjustable from 0.8 V to 1.8 V. |
| 6 | OUT | output | Regulated output voltage, adjustable from 0.8 V to 1.8 V. |
| 7 | BIAS | input | Supply for the internal control and reference circuitry; VBIAS is 3 V to 5.5 V for VOUT of 0.8 V to 1.2 V and 4.5 V to 5.5 V for VOUT above 1.2 V up to 1.8 V. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
