The LD1117AS18TR is a 1.8V fixed output low-dropout (LDO) Linear Regulator able to provide up to 1A of output current. High efficiency is assured by an NPN pass transistor. Only a very common 10µF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C.
1.15V Typical at IOUT = 1A, 25°C low dropout voltage
5mA Typical at 25°C very low quiescent current
Internal current and thermal limit
80dB Typical at 25°C high supply voltage rejection
