Texas Instruments Voltage Regulators - Linear LP2985IBLX-285

The LP2985IBLX-285 is a micropower linear voltage regulator designed to deliver a fixed output voltage with a maximum output current of 150 mA. It features an ultra-low dropout voltage of typically 300 mV at 150 mA load and 7 mV at 1 mA load, making it suitable for battery-powered applications. The device operates with a low ground pin current of approximately 850 ¬µA at full load and less than 1 ¬µA in sleep mode, enhancing its efficiency. This regulator is stable with low equivalent series resistance (ESR) output capacitors, allowing the use of ceramic capacitors, which can help minimize board space. The LP2985IBLX-285 offers a precision output voltage tolerance of 1% and is available in multiple voltage options ranging from 2.5V to 5.0V, with custom voltages available upon request. It also includes overtemperature and overcurrent protection features, ensuring reliable operation across a junction temperature range of -40¬8C to +125¬8C. The device is packaged in a compact micro SMD format, making it ideal for applications where space is a constraint, such as in cellular phones, laptops, and portable electronic devices.
