TPS7A0222DQNR Linear Voltage Regulator IC Positive Fixed 1 Output 200mA 4-X2SON (1x1)
Texas Instruments TPS7A02 Low-Dropout (LDO) Linear Regulator
Texas Instruments TPS7A02 Low-Dropout (LDO) Linear Regulator is an ultra-small, ultra-low quiescent current LDO regulator that can source 200mA with excellent transient performance. The TPS7A02, with an ultra-low IQ of 25nA, is designed specifically for applications where a very-low quiescent current is a critical parameter. This device maintains low IQ consumption even in dropout mode to further increase the battery life. When in shutdown or disabled mode, the device consumes ultra-low, 3nA IQ that helps increase the shelf life of the battery. The TPS7A02 has an output range of 0.8V to 5.0V available in 50mV steps to support the lower core voltages of modern microcontrollers (MCUs). The TPS7A02 features a smart enable circuit with an internally controlled pulldown resistor that keeps the LDO disabled even when the EN pin is left floating and helps minimize the external components used to pull-down the EN pin. This circuit also helps minimize the current drawn through the external pull-down circuit when the device is enabled. The TPS7A02 is fully specified for TJ = –40°C to +125°C operation.
