TEXAS INSTRUMENTS Low Dropout Voltage Regulator 500mA TO-220
TEXAS INSTRUMENTS 5V fixed positive voltage regulator offering 500mA output, low dropout & reverse battery protection.
This positive voltage regulator from TEXAS INSTRUMENTS is capable of supplying up to 500mA of load current, making it a reliable choice for various electronic applications. The use of a PNP power transistor provides a low dropout voltage characteristic, ensuring stable performance even when the input voltage is close to the output voltage.
With a load current of 500mA, the minimum input to output voltage differential required for the output to remain in regulation is typically just 0.5V, with an ensured maximum of 1V over the full operating temperature range. Special circuitry has been incorporated to minimise the quiescent current to typically only 10mA when operating with a full 500mA load and a voltage differential greater than 3V.
Protection and Reliability
Designed for demanding environments, this regulator is fully specified for operation over a wide temperature range from −40°C to 125°C. It features comprehensive internal protection mechanisms, including short circuit and thermal overload protection, alongside reverse battery protection to safeguard your circuitry.
