LM79L15

HTC Korea TAEJIN Tech · Linear Voltage Regulators (LDO) · TO-92-3

LM79L15 from HTC Korea TAEJIN Tech, in a TO-92-3. 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 GND power_in Ground reference pin for the negative regulator, as listed in the pin description table for the TO-92 / SOT-89 3-lead package.
2 VIN power_in Unregulated negative input voltage; for the LM79L15 the recommended input range is -17.5 V to -30 V, with an absolute maximum of -35 V.
3 VOUT power_out Regulated negative output voltage of -15 V nominal (-14.25 V to -15.75 V over 0 to 125 °C at 1 mA ≤ Io ≤ 70 mA), rated for output current up to 100 mA.
