The LT1121IZ-5#PBF is a fixed 5V low dropout linear regulator from Linear Technology, delivering up to 150mA of output current. Its low 50µA quiescent current and 0.7V dropout at full load make it suitable for battery-powered and energy-sensitive applications. The TO-92-3 package offers a compact, through-hole solution for space-constrained designs.
- Extended Battery Life: Ultra-low 50µA quiescent current minimizes standby power draw.
- Stable 5V Output: Fixed output ensures consistent performance for logic and sensor circuits.
- Effective Ripple Rejection: 58dB PSRR at 120Hz filters AC line noise.
- Compact Through-Hole Package: TO-92-3 simplifies prototyping and manual assembly.
