The LP5900TL-1.9 is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 1.9V with a maximum output current of 150 mA. It operates within an input voltage range of 2.5V to 5.5V and features low output voltage noise of 6.5 OºV RMS, making it suitable for RF and analog applications. The device boasts a high power supply rejection ratio (PSRR) of 75 dB at 1 kHz, ensuring stable performance in noisy environments. This regulator requires only 0.47 OºF ceramic capacitors for both input and output, eliminating the need for a noise bypass capacitor. It includes logic-controlled enable functionality, thermal overload protection, and short-circuit protection. The LP5900TL-1.9 operates effectively across a junction temperature range of -40¬8C to +125¬8C. It is available in a compact 4-bump micro SMD package, making it suitable for space-constrained applications such as cellular phones and wireless LAN devices.
