APL5611
APL5611 is Low Dropout Linear Regulator Controller manufactured by ANPEC.
APL5611/A
Low Dropout Linear Regulator Controller
Features
General Description
- Wide Supply Voltage Range from 4.5 to 13.5V
The APL5611/A is a low dropout linear regulator controller.
- High Output Accuracy Over Operating Temperature The APL5611/A could drive an external N-Channel and Loading Ranges
MOSFET and provide an adjustable output by using an
- Fast Transient Response external resistive divider.
- Power-On-Reset Monitoring on VCC
- Programmable Soft-Start
- Low Shutdown Current
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
- Enable Control Function circuit condition. The soft-start of output voltage is adjust-
- Under-Voltage Protection able by the external capacitor on SS pin. Moreover, the
- Two Versions of IC Available:
APL5611/A can be enabled by other power system;
- APL5611: UVP Activated after VOUT is Ready
- APL5611A: UVP Activated after VCC is Supplied
- SOT-23-6 Package 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.
