TK73280MIL datasheet

 

Description

The TK73280MIL is a controller IC for a low dropout voltage regulator. The TK732xx and the external PNP power transistor provide standard output voltages from 2 to 11 V and output current from 100 mA to 5 A. By utilizing an external PNP power transistor, low dropout voltage at high current can be readily achieved. The internal electronic switch can be controlled by TTL or CMOS logic levels. The device is in the “on” state when the control pin is pulled to a high logic level. A pin for a bypass capacitor, which connects to the internal circuitry, is provided to lower the overall output noise level.

 

Features

1. Up to 5 A Output Current Capability With External PNP Transistor
2. Internal Short Circuit Protection
3. Excellent Load Regulation
4. CMOS/TTL-Compatible On/Off Switch
5. Internal Reverse Bias Current Protection Switch
6. Internal Thermal Shutdown
7. Broad Operating Voltage Range
8. High Impedance VSENSE Pin (Off Mode)
9. Continuous and Pulsed Current Modes

Applications

1. Battery Powered Systems
2. Cellular/Cordless Telephones
3. Radio Control Systems
4. Wireless Communications Systems
5. Portable Instrumentations
6. Portable Computers
7. Personal Digital Assistants
8. Local Area Network (LAN) Receivers
9. Lithium Ion Battery Chargers
10. Power Recovery for Microprocessors

AIC1117A-33CT Datasheet – 3.3V, Dropout Adjustable Regulator

Posted on by pinout

Part Number: AIC1117A-33CT

Function: 1A, Low Dropout Positive Adjustable Regulator

Package: TO-220, TO-252, TO-263, SOT-223 Type

Manufacturer: Analog Intergrations

Pinouts:

AIC1117A-33CT datasheet

 

Description

The AIC1117A is a  low dropout three terminal regulator with 1A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed 2.85V, 3.3V, 5V. Dropout is guaranteed at a maximum of 1.5V at maximum output current. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Internal current and thermal limiting provides protection against any overload condition that would create excessive junction temperatures.

Features

1. Dropout Voltage 1.3V at 1A Output Current.
2. Fast Transient Response.
3. Line Regulation typically at 0.015%.
4. Load Regulation typically at 0.1%.
5. Internal Thermal and Current Limiting.

Applications

1. Post Regulator for Switching Supply.
2. Active SCSI Termination.
3. Battery Chargers.
4. Constant-Current Regulators.
5. Motherboard Clock Supplies.
