General 

Description

The APL5523 is a dual low dropout regulator with output1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL5223 has been optimized. The dropout voltages are guaranteed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for output 2. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.

Features

1. Fixed  Output Voltage :

(1)  VOUT1=3.3V/500mA

(2) Output  2  Dropout  V oltage : 0.9V  (at 300mA)

3. Stable with 4.7mF Output Capacitor(at VOUT1

4. Stable with 2.2mF Output Capacitor(at VOUT2)

5. Built-In Thermal Protection

6. Built-In Current-Limit Protection

7. Fast Transient Response

8. Short Setting Time

9. SOP-8 and SOP-8P Packages Available

10. Lead Free and Green Devices Available(RoHS  Compliant)

Applications

1. Desktop Computer

2. Networking Systems

3. Optical Data Storage Systems

STR-W6553A Datasheet PDF – Switching Regulator

Part Number: STR-W6553A

Function : Off-Line Quasi-Resonant Flyback Switching Regulator

Package : TO-220 Type

Manufacturer: Sanken, Allegro

STR-W6553A datasheet

Description

The STR-W6553A is a quasi-resonant regulator specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power supplies. It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET. The regulator exhibits only low-level high-frequency EMI noise because of soft switching of the MOSFET close to ground (bottom point). A bottom-skip function minimizes an increase of operational frequency during light loads to improve system efficiency over the entire load range.
