TLV74310PDQNR LDO regulator
The TLV74310PDQNR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments, belonging to the TLV743P family of low-quiescent-current, high-performance regulators designed to deliver up to 300 mA of output current with a fixed 1.0 V output. This device integrates an enable pin along with active output discharge functionality, making it well suited for power-sensitive, battery-operated, and space-constrained applications where clean and stable voltage rails are essential. As a modern CMOS-based LDO, it combines excellent line and load transient performance with ultra-compact packaging, serving as an ideal companion regulator for processors, sensors, and RF modules in portable electronics.
In terms of protection and control features, the TLV74310PDQNR incorporates foldback overcurrent protection that limits inrush current during power-up and enable transitions, a critical safeguard for battery-powered systems. It also includes short-circuit protection, thermal shutdown with automatic recovery, and input undervoltage lockout (UVLO) to ensure robust operation under fault conditions. An active output discharge circuit rapidly discharges the output load capacitor when the device is disabled, preventing residual voltage from affecting downstream circuitry and enabling predictable power sequencing. These integrated safeguards enhance system reliability without requiring additional external protection components. Its target applications include smartphones, tablets, wearable devices, WLAN modules, camera modules, laptops, portable medical instruments, and other low-power systems where miniature form factor, low noise, and high efficiency are paramount.
Alternative voltage regulators
● TLV73310PDQNR: A capacitor-free, 300 mA, 1.0 V LDO in the same X2SON-4 package that eliminates the need for an external output capacitor, further reducing component count and solution size.
● TLV74312PDQNR: A 1.2 V output sibling in the TLV743P family sharing the same 300 mA current capability and X2SON-4 package for designs requiring a slightly higher core voltage rail.
● TLV74330PDQNR: A 3.0 V output variant in the same X2SON-4 package with 125 mV ultra-low dropout at 300 mA, suited for higher-voltage analog and I/O regulation.
● TLV74210PDQNR: A 200 mA, 1.0 V LDO with 0.5% accuracy and 55 dB PSRR at 1 MHz in X2SON-4, serving as a lower-current, higher-precision alternative for noise-sensitive loads.
