Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92
AS78L05ZTR-E1 from Diodes Incorporated, in a TO-92. 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 | OUTPUT | power_out | Regulated 5 V output; the datasheet gives VOUT of 4.75 V to 5.25 V for 7 V ≤ VIN ≤ 20 V, 1 mA ≤ IOUT ≤ 100 mA, and PD ≤ 0.75 W. |
| 2 | GND | power_in | Common ground reference for the input and output; the datasheet gives no separate electrical limit for this pin. |
| 3 | INPUT | power_in | Unregulated supply input with an absolute maximum of 36 V, and dropout of 1.7 V at 40 mA and 1.8 V at 100 mA. |
