APL5611/A
Active
Low Dropout Linear Regulator Controller
Features
- APL5611A: UVP Activated after VCC is Supplied
General Description
The APL5611/A is a low dropout linear regulator controller. The APL5611/A could drive an external N-Channel MOSFET and provide an adjustable output by using an external resistive divider. The APL5611/A integrates various functions. For example, a Power-On-Reset (POR) circuit monitors VCC supply voltage to prevent wrong operations; the function of Under-Voltage Protection (UVP) protects the device from short circuit condition. The soft-start of output voltage is adjustable by the external capacitor on SS pin. Moreover, the APL5611/A can be enabled by other power system; namely, holding the EN above 1.6V enables output and pulling the EN under 0.4 disables output. The APL5611/A is available in a SOT-23-6 package.
Features
- Wide Supply Voltage Range from 4.5 to 13.5V
- High Output Accuracy Over Operating Temperature and Loading Ranges
- Fast Transient Response
- Power-On-Reset Monitoring on VCC
- Programmable Soft-Start
- Low Shutdown Current
- Enable Control Function
- Under-Voltage Protection
- Two Versions of IC Available:
- APL5611A: UVP Activated after VCC is Supplied
- SOT-23-6 Package
- Lead Free and Green Devices Available (RoHS Compliant)
