Part Number: LD2982AM32R

Function: 3.2V, 50mA, VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR

Package: SOT23-5L Type

Manufacturer: STMicroelectronics

Description

The LD2982, LD2982AM32R is a 50 mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems.

In sleep mode quiescent current is less than 1 µA when INHIBIT pin is pulled low. Shutdown logic control function is available on pin 3 (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.

An external capacitor CBYP = 10 nF connected between bypass pin and GND reduce the noise to 30 µVrms.

Features

1. VERY LOW DROPOUT VOLTAGE (120mV AT 50mA AND 7mV AT 1mA LOAD)

2. VERY LOW QUIESCENT CURRENT (375mA TYP. AT 50mA LOAD AND 75mA AT 1mA)

3. OUTPUT CURRENT UP TO 50mA

4. LOGIC CONTROLLED ELECTRONIC SHUTDOWN

Description

The TPS752xx and TPS754xx, TPS75201QPWPQ1 are low-dropout regulators with integrated power-on reset and power good (PG) functions, respectively. These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233, TPS75433). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS752xx and TPS754xx are designed to have fast transient response for larger load current changes.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 210 mV at an output current of 2 A for the TPS75x33) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 75 µA over the full range of output current, 1 mA to 2 A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
