Introduction

Low dropout linear voltage regulator for power management applications.

Product Features and Performance

LDO (Low Drop Out) characteristic provides efficient operation with a low voltage difference between input and output.

Fixed output voltage of 2.5V stabilizes at a consistent level.

Supports up to 18V input voltage, suitable for various applications.

High output current capacity of 1.2A for demanding circuits.

Excellent Power Supply Rejection Ratio (PSRR) minimizes noise from input power source.

Low quiescent current of 500 µA improves overall efficiency.

Surface mount package for compact PCB design.

Product Advantages

Robust overcurrent and overtemperature protection enhance reliability.

Under Voltage Lockout (UVLO) prevents operation under unsafe voltage conditions.

Capable of dealing with high-temperature ranges from -40°C to 125°C.

High PSRR ensures stable output voltage despite input noise or fluctuations.
