Texas Instruments High-Performance Analog Voltage Regulators - Linear LP3985ITLX-2.5

The LP3985ITLX-2.5 is a micropower, low-noise, ultra low-dropout CMOS voltage regulator designed for portable and wireless applications. It provides a stable output of 2.5V with a maximum output current of 150mA, making it suitable for battery-powered systems. The device features a low dropout voltage of 100mV at full load and consumes less than 1.5¬µA in shutdown mode, which helps prolong battery life. This regulator is stable with a small 1¬µF ceramic or high-quality tantalum output capacitor, allowing for compact circuit designs with a total application area of less than 2.0mm x 2.5mm. The LP3985ITLX-2.5 has a fast turn-on time of less than 200¬µs and offers excellent power supply rejection ratio (PSRR) of over 50dB at low frequencies, ensuring minimal output noise. It operates over a temperature range of -40AöC to +125AöC, making it suitable for a variety of environments. The device is available in a micro SMD package, facilitating integration into space-constrained applications.
