Technical Specifications:

The LP3995ITLX-1.6 operates with an input voltage range typically from 2.5V to 6V, providing a regulated 1.6V output. The low dropout voltage of 100mV at 150mA ensures efficient operation even when the input voltage is close to the output voltage. The output voltage accuracy is maintained within ±2% over a wide temperature range. The low quiescent current of 20µA minimizes power consumption when the device is in standby mode. The device is stable with ceramic output capacitors, which are smaller and more cost-effective than other types of capacitors. Built-in current limiting and thermal shutdown protection mechanisms safeguard the device and the load from potential damage due to overcurrent or overtemperature conditions. The LP3995ITLX-1.6 is available in a tiny 5-Pin LLP (Leadless Leadframe Package), which offers excellent thermal performance and saves valuable board space. Its operating temperature range is -40°C to +125°C.

In mobile phones and tablets, the LP3995ITLX-1.6 often powers core logic, memory, or other low-voltage components. Its small size and efficiency are crucial for these applications. The device's ability to operate with low input voltages extends battery life, a key requirement for portable devices. The thermal shutdown feature protects the regulator and the load from damage due to overheating, ensuring reliable operation even under demanding conditions.
