Description

The APL5536 is a dual channel low dropout linear regulator, which operates from 2.5V to 5.5V input voltage and delivers up to 300mA output current at each channel. Typical dropout voltage is only 270mV at 300mA. The APL5536  with low quiescent current, high PSRR, and low noise is ideal for battery powered system appliances.

Other features include logic-controlled shutdown mode, over-temperature protection, short-circuit current-limit, and current-limit protection to ensure specified output current. The APL5536 is available in SOT-23-6, TSOT-23-6A, and TDFN1.6×1.6-6 packages.

Part Number: LM2940-N

Function: 1A, Low Dropout Regulator

Package: TO-220, DIP 16, DDPAK, TO-263 Type

Manufacturer: Texas Instruments

Description

The LM2940-N / LM2940C positive voltage regulator features the ability to source 1A of output current with a dropout voltage of typically 0.5V and a maximum of 1V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN− VOUT≤ 3V).

Features

• Dropout Voltage Typically 0.5V @IO= 1A
• Output Current in Excess of 1A
• Output Voltage Trimmed Before Assembly
• Reverse Battery Protection
• Internal Short Circuit Current Limit
• Mirror Image Insertion Protection
• P+ Product Enhancement Tested

Applications:

1. Post Regulator for Switching Supplies

2. Logic Power Supplies

3. Industrial Instrumentation
