TPS7A02 200 mA LDO Linear Regulator with Fast Transient
Texas Instruments' nanopower IQ, 25 nA regulator is suitable for applications such as wearable electronics
Texas Instruments' TPS7A02 ultra-small, ultra-low quiescent current low-dropout (LDO) linear regulator can source 200 mA with excellent transient performance. The TPS7A02 offers an ultra-low IQ of 25 nA making it suitable for applications that require an ultra-low quiescent current. 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 3 nA IQ that helps increase the shelf life of the battery.
The TPS7A02 offers an output range of 0.8 V to 5.0 V available in 50 mV steps to support the lower core voltages of modern microcontrollers (MCUs). The device 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 pulldown the EN-pin. This circuit helps minimize the current that is drawn through the external pulldown circuit when the device is enabled. The TPS7A02 is fully specified for an operating temperature range of -40°C to +125°C.
