TPS7A0333PDQNR3

TPS7A03 is an ultra-small, ultra-low quiescent current LDO linear regulator capable of delivering 200mA with excellent transient performance. The TPS7A03 features an ultra-low IQ (200nA), 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 draws an ultra-low IQ of 3nA, helping to extend battery shelf life. The TPS7A03 output voltage range is 0.8V to 5.0V in 50mV steps, supporting the lower core voltages of modern MCUs. The TPS7A03 features an intelligent enable circuit with an internal control pull-down resistor that keeps the LDO disabled even when the EN pin is left floating, helping to minimize external components required for pulling down the EN pin. This circuit also helps minimize current flow through the external pull-down circuit when the device is in the disabled state. The TPS7A03 is rated for an operating junction temperature range of TJ = -40°C to +125°C.
