TPS7A21/TPA7A21-Q1 500mA Ultra LDO Regulators

Texas Instruments TPS7A21/TPA7A21-Q1 500mA Ultra-Low Dropout (LDO) Voltage Regulators are linear voltage regulators that can source 500mA 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. Innovative design techniques result in low-noise performance without adding an external noise bypass capacitor. The TPS7A21/TPA7A21-Q1 low quiescent current is a good choice for battery-powered systems. The Texas Instruments TPS7A21/TPA7A21-Q1 has a 2.0V to 6.0V input voltage range and a 0.8V to 5.5V output voltage range that supports various system requirements. The internal precision reference circuit enables excellent accuracy; the maximum output voltage tolerance is 1.5% over load, line, and temperature variations.
