Description
General part information
TPS7A21-Q1 Series
The TPS7A21-Q1 is a small, low-dropout (LDO) linear voltage regulator that sources 500mA of output current. The device provides low noise, high PSRR, and excellent load and line transient performance to meet the requirements of RF and other sensitive analog circuits in automotive applications. Innovative design techniques result in low-noise performance without the addition of an external noise bypass capacitor. The TPS7A21-Q1 low quiescent current is a good choice for low-power systems. The 2.0V to 6.0V input voltage range and 0.8V to 5.5V output voltage range support a variety of system requirements.
An internal soft-start circuit helps control inrush current, thus minimizing the input voltage drop during start-up. The LDO is stable with small ceramic capacitors, allowing for a small overall solution size.
A smart enable input circuit with an internally controlled pulldown resistor keeps the LDO disabled even when the EN pin is unconnected. This circuit also helps eliminate external components that are otherwise required to pull down the EN input.
