TLV70733DQNR1 LDO regulator IC Positive Fixed 1 Output 200mA
The TLV70733DQNR1 from Texas Instruments is a 3.3V, 200mA low-dropout (LDO) linear voltage regulator engineered for space-constrained and power-sensitive portable electronics. Housed in an ultra-miniature 1mm × 1mm X2SON (DQN-4) package, this CMOS-based LDO operates from a 2V to 5.5V input and delivers a fixed 3.3V output with a high typical accuracy of ±0.5%. It features an enable (EN) pin for power sequencing and integrates comprehensive protection features including thermal shutdown and overcurrent limit, making it a robust power management solution for battery-powered applications where board area is at a premium.
This LDO distinguishes itself with an exceptional balance of low quiescent current (IQ = 25 µA typical) and high power supply rejection ratio (PSRR), achieving approximately 70 dB at 100 Hz to effectively filter input noise. A significant design advantage is its stability with a very small 0.1 µF ceramic output capacitor, minimizing the solution footprint and BOM cost while simplifying compensation design. The regulator exhibits a low dropout voltage of around 250 mV at 150 mA load, ensuring efficient regulation even as battery voltage decays. Its wide operating junction temperature range of -40°C to +125°C ensures reliable performance in demanding environmental conditions.
