3 Description

The TLV742P series of low-dropout linear voltage regulators (LDOs) are optimized to providing excellent performance by supporting a wide output voltage range. The LDOs can directly regulate a single cell Li-ion battery input-to-output voltage as low as 0.85 V. If used to post-regulate a DC-DC converter output, the high PSRR of 55 dB at 1 MHz suppresses ripple to provide a stable low-noise, well-regulated V_OUT.

The TLV742P has an active output discharge feature that helps ensure the output is kept low while the system is disabled, in standby mode, or in sleep mode. Additionally, overcurrent protection is present to protect the device in the event of an output short along with thermal shutdown to prevent overheating.

The TLV742P series of voltage regulators are available in a 1 mm × 1 mm X2SON package to minimize PCB area.

Pin Functions

PIN		I/O	DESCRIPTION
NAME	NO.	I/O	DESCRIPTION
EN	3	I	Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode. For TLV742P, output voltage is discharged through an internal 120-Ω resistor when device is shut down.
GND	2	—	Ground pin
IN	4	I	Input pin. For good transient performance, place a small 1-µF ceramic capacitor from this pin to ground. See Input and Output Capacitor Requirements for more details.
OUT	1	O	Regulated output voltage pin. A small 1-μF ceramic capacitor is required from this pin to ground to ensure stability. See Input and Output Capacitor Requirements for more details.
Thermal pad	—	—	The thermal pad is electrically connected to the GND node. Connect to the GND plane for improved thermal performance.
