The Texas Instruments TPS78342DDCT is a high-performance, low-dropout (LDO) linear voltage regulator. It is specifically designed for battery-powered applications where ultralow quiescent current is a critical parameter. This LDO offers a 150-mA output current capability with an ultralow quiescent current of just 500 nA.
The TPS78342DDCT provides a fixed 4.2V output voltage and operates over an input voltage range of 2.2 V to 5.5 V. It boasts a low dropout voltage of 130 mV at 150 mA and 85°C, ensuring efficient power regulation. The regulator maintains 3% accuracy over load, line, and temperature variations.
Key features include thermal shutdown and overcurrent protection for enhanced reliability. The device is stable with a 1.0-µF ceramic capacitor and features a CMOS logic-level-compatible enable pin. It is housed in a small SOT-23-5 Thin (TSOT-23-5) package, making it suitable for space-constrained designs.
This LDO is ideal for microprocessors, microcontrollers, and other portable electronic devices requiring efficient and stable power management. The absence of pulldown circuitry at the output offers flexibility in output capacitor selection.
