STMICROELECTRONICS LM317LZ-AP Adjustable Voltage Regulator, 100mA, TO-92-3

The STMICROELECTRONICS LM317LZ-AP is a low-current adjustable voltage regulator that delivers an output voltage from 1.2V to 37V with a load current of up to 100mA. This versatile component requires only a resistive divider to set the nominal output voltage, eliminating the need to stock multiple fixed regulators and simplifying your design process.

Built for reliability, the device includes thermal overload protection, short-circuit protection, and output transition safe area compensation, ensuring stable operation under demanding conditions. Its ability to float for high-voltage applications and typical adjustment pin current of only 50µA make it a flexible choice for a wide range of electronic projects.

Key specifications include a typical reference voltage of 1.25V, a maximum output current of 200mA (at VI - VO = 3 to 13V), and a supply voltage rejection of 65dB (typ). The regulator operates over a junction temperature range of 0°C to 125°C and comes in a compact TO-92 package with through-hole mounting for easy integration.
