Product Introduction
The LKP85512QF is a low-dropout linear regulator that provides power management solutions for a wide range of applications. Its programmable soft-start function reduces capacitive inrush current during system startup, thereby minimizing input power supply stress. This device is well-suited for powering various processors and ASICs. With enable input and power-good output, it provides solutions for applications with specific startup sequencing requirements, and can maintain system stability without an external output capacitor or with only a small ceramic output capacitor. The output voltage can be set using the formula V_OUT = 0.8V × (1 + R1/R2).
Features
- Input voltage range: 1.1V ~ 5.5V
- Adjustable output voltage range: 0.8V ~ 3.6V
- Maximum output current: 3A
- Low dropout: 115mV @ 3A
- Soft-start pin enables linear startup; rise time set via external capacitor
- Input voltage down to 0.9V with external bias supply
- Stable with any output capacitor or no output capacitor
- Fast transient response
- Package: QFN20 (5.00mm × 5.00mm × 0.75mm)
Applications
- - FPGA applications - DSP core and I/O voltage - Post-regulation circuits - Applications with special startup or sequencing requirements - Hot-swap and inrush control
