Description

The APL5308 / APL5309 series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and del i ver up to 300mA. Typical dropout voltage is only 400mV at 300mA loading. Designed for use in battery-powered system, the low 60mA qui escent current makes it an ideal choice.

Design with an internal P-channel MOSFET pass transistor, the APL5308/9 maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown  p rotection current limit protection to ensure specified output current and controlled short-circuit current . The APL5308 / APL5309 regulators come in a miniature SOT-23-3, SOT-23-5, and SOT-89 packages.

Features

• Low Quiescent Current : 60mA (No load)
• Low Dropout V oltage : 400mV (@300mA)
• Fixed Output V oltage : 1.5V ~ 4.5V by Step 0.1V Increment

Part Number: TPS7A4001

Function: 100V Input Voltage, 50mA, Adjustable Low-dropout Voltage Regulator

Package: MSOP-8 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The TPS7A4001 is a very high voltage-tolerant linear regulator that offers the benefits of a thermally-enhanced package (MSOP-8), and is able to withstand continuous dc or transient input voltages of up to 100V.

The device is stable with any output capacitance greater than 4.7µF and any input capacitance greater than 1µF (over temperature and tolerance). Therefore, implementations of this device require minimal board space because of its miniaturized packaging (MSOP-8) and a potentially small output capacitor. In addition, the TPS7A4001 offers an enable pin (EN) compatible with standard CMOS logic to enable a low-current shutdown mode.

The TPS7A4001 has an internal thermal shutdown and current limiting to protect the system during fault conditions.

Features

1. Low Quiescent Current : 25 µA

2. Quiescent Current at Shutdown : 4.1 µA

3. Maximum Output Current : 50 mA

4. CMOS Logic-Level-Compatible Enable Pin

5. Adjustable Output Voltage from about 1.175 to 90 V
