The TLV73311PDQNR is a 1.1-V fixed-output low-dropout linear regulator from Texas Instruments. It belongs to the TLV733P family of ultra-small, low-quiescent-current LDOs designed to provide up to 300 mA of regulated output current.
The device operates from a 1.4 V to 5.5 V input supply and provides a regulated 1.1 V output. With a typical quiescent current of 34 µA, it is suitable for battery-powered and low-power embedded systems where efficient power management is important.
The TLV733 family uses a capacitor-free architecture that remains stable without an input or output capacitor. This can reduce external component count, board area and startup inrush current. Ceramic output capacitors can also be used when required by the application.
The family provides 1% typical accuracy and 1.4% maximum accuracy, together with high power-supply rejection. TI specifies 50 dB typical PSRR at 1 kHz and 28 dB at 100 kHz, helping suppress supply noise on sensitive low-voltage rails.
The TLV733 series also incorporates foldback overcurrent protection and an active pull-down circuit that discharges the output when the regulator is disabled. These functions help improve device behavior during startup, shutdown and overload conditions.
The X2SON (DQN) package measures only 1.0 mm × 1.0 mm, making the TLV73311PDQNR suitable for highly space-constrained electronics, including portable devices, sensors, embedded systems and compact power-management circuits.
