The device features 35uA typical quiescent current, ultra-low 37mV dropout at 50mA, and 68dB PSRR at 1kHz. The 1.8V output is commonly used for MCU\/FPGA core supply and DDR memory. The 2V to 5.5V input range supports Li-ion battery and 3.3V\/5V rail operation. The enable pin provides 1uA shutdown mode. The DBVT suffix denotes SOT-23-5 package with tape and reel packaging.","working_principle":"The TLV70218DBVT operates as a low-IQ LDO linear regulator with 1.8V fixed output. (1) The P-channel MOSFET pass element provides very low dropout voltage: only 37mV at 50mA load, making it efficient for 1.8V rails powered from 2V or higher. The precision bandgap reference and error amplifier maintain +\/-2% output voltage accuracy. (2) The 35uA quiescent current supports always-on applications where the regulator must remain active with minimal battery drain. In shutdown mode (EN pin low), the quiescent current drops to 1uA, extending battery life in portable devices. (3) The 68dB PSRR at 1kHz provides excellent input ripple rejection, critical for noise-sensitive 1.8V analog and RF supply rails. The stability with only 0.1uF effective output capacitance enables the use of very small capacitors, saving board space in compact designs.","pin_description":"
