APL5932A/B/C/D 3A, Ultra Low Dropout (0.23V Typical) Linear Regulator Features • General Description The APL5932A/B/C/D is a 3A ultra low dropout linear regulator. The IC needs two supply voltages, one is a Ultra Low Dropout - 0.23V (Typical) at 3A Output Current • control voltage (VCNTL) for the control circuitry, the other is a main supply Voltage(VIN) for power conversion, to re- Low ESR output Capasitor (Milti-layer Chip Capasitors (MLCC)) Applicable • • duce power dissipation and provide extremely low dropout voltage. 0.8V Reference Voltage High Output Accuracy The APL5932A/B/C/D integrates many functions. A PowerOn-Reset (POR) circuit monitors both supply voltages on - ±1.5% Over Line, Load, and Temperature Range • • • Fast Transient Response VCNTL and VIN pins to prevent erroneous operations. The functions of thermal shutdown and current-limit protect Adjustable Output Voltage the device against thermal and current over-loads. A POK indicates that the output voltage status with a delay time Power-On-Reset Monitoring on Both VCNTL and VIN Pins • • • • • • set internally. It can control other converter for power sequence. APL5932A/B/C/D can be enabled by other Internal Soft-Start Current-Limit and Short Current-Limit Protections power systems. Pulling and holding the EN voltage below 0.4V or ENB above 1.2V will shuts off the output. Thermal Shutdown with Hysteresis Open-Drain VOUT Voltage Indicator (POK) The APL5932A/B/C/D is available in a SOP-8P package which features small size as SOP-8 and an Exposed Low Shutdown Quiescent Current (< 30µA ) Built in Shutdown/Enable Control with floating high/ Pad to reduce the junction-to-case resistance to extend power range of applications. low Function • Simple SOP-8P and TDFN3x3-10 Packages with Exposed Pad • Lead Free and Green Devices Available Simplified Application Circuit (RoHS Compliant) Applications • • • VCNTL Motherboards, VGA Cards VIN Notebook PCs VCNTL POK Add-in Cards VIN POK VOUT VOUT APL5932 A/B/C/D EN Enable EN FB GND Optional ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
