Texas Instruments Voltage Regulators - Linear REG102GA-3/2K5

The REG102GA-3/2K5 is a low-dropout linear voltage regulator designed to provide a stable output current of up to 250mA. It features an ultra-low dropout voltage of 150mV at full load, which enhances efficiency in battery-powered applications. The device operates within a supply input voltage range of -0.3V to 12V and has a very low ground pin current of 600¬µA during operation, dropping to 0.01¬µA when disabled. This regulator does not require an output capacitor for stability, simplifying design and reducing component costs. It offers fast transient response and low output noise, typically 28¬µVrms, making it suitable for sensitive applications such as portable communication devices and personal digital assistants. The output voltage accuracy is ¬±1.5%, maintained over a temperature range of -40¬8C to +85¬8C. The REG102GA-3/2K5 includes built-in thermal protection and foldback current limiting to safeguard against overload conditions. It is available in compact surface-mount packages, including SOT23-5, SOT223-5, and SO-8, making it a versatile choice for space-constrained designs.
