TLV7A0330PDBVR

The TLV7A03 is an ultra-small, ultra-low quiescent current LDO regulator capable of delivering 200mA output current with excellent transient performance. With an ultra-low IQ of 250nA, the TLV7A03 is specifically designed for applications where ultra-low quiescent current is a critical parameter. The device maintains low IQ consumption even in dropout mode, further extending battery life. In shutdown or disable mode, the device consumes only 3nA IQ, helping to extend battery shelf life. The TLV7A03 output voltage range is 0.8V to 5.0V with 50mV output steps, supporting the lower core voltages of modern MCUs. The TLV7A03 features an intelligent enable circuit with an internally controlled pull-down resistor that keeps the LDO in the disabled state even when the EN pin is floating. This circuit reduces the number of external components required for EN pin pull-down and minimizes current consumption from external pull-down circuitry when the device is enabled. The TLV7A03 is fully specified over an operating junction temperature range of -40°C to +125°C.
