Description

The TLV1117LV series of low-dropout (LDO) linear regulators is a low input voltage version of the popular 1117 voltage regulator. The TLV1117 is an extremely low-power device that consumes 500 times lower quiescent current than traditional 1117 voltage regulators, making it suitable for applications that mandate very low standby current. The device family of LDOs is also stable with 0 mA of load current; there is no minimum load requirement, making it an ideal choice for applications where the regulator is required to power very small loads during standby in addition to large currents on the order of 1 A during normal operation. The TLV1117LV offers excellent line and load transient performance, resulting in very small magnitude undershoots and overshoots of output voltage when the load current requirement changes from less than 1 mA to more than 500 mA.

Part Number: TPS76801QD

Device Marking : 76801

Function: FAST TRANSIENT RESPONSE, 1-A LOW-DROPOUT VOLTAGE REGULATOR

Package: SOIC-8 (D) and TSSOP-20 (PWP) Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

This is 1A, 10V, Low-dropout Voltage Regulator.

This device is designed to have a fast transient response and be stable with 10 µF capacitors. This combination provides high performance at a reasonable cost. Since the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 230 mV at an output current of 1 A for the TPS76850) and is directly proportional to the output current.

Additionally, because the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over the full range of output current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a shutdown mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ= 25°C. Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator.

Features

• Input Voltage Range: 2.7 V to 10 V

• Low-Dropout Voltage: 230 mV typical at 1 A(TPS76850)

• 2% Tolerance Over Specified Conditions for Fixed-Output Versions

• Open Drain Power Good (See TPS767xx for Power-On Reset With 200-ms Delay Option)

• Ultralow 85 µA Typical Quiescent Current

• Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, 5.0-V Fixed Output and Adjustable (1.2 V to 5.5 V) Versions

• Fast Transient Response

• Thermal Shutdown Protection
