Description
The ZTP1117SA is a low-dropout (LDO) linear voltage regulator designed to provide stable output voltages with minimal power loss. It supports fixed output options (e.g., 1.8V, 2.5V, 3.3V, 5V) and adjustable versions (1.25V–15V), delivering up to 1A of current with a typical dropout voltage of 1.1V.
Key features include:
- Low dropout voltage (suitable for battery-powered devices).
- High accuracy (±1% output tolerance).
- Thermal and short-circuit protection.
- Low quiescent current (~5mA).
Common applications include powering microcontrollers, sensors, and other low-voltage circuits in consumer electronics, IoT devices, and industrial systems. The TO-252 (DPAK) package ensures efficient heat dissipation.
For adjustable versions, external resistors set the output voltage. Always refer to the datasheet for specific wiring and thermal considerations.
