The LP3981-25B5F is a linear voltage regulator (LDO) with SOT-23-5 form factor and RoHS compliant. This low power regulator is manufactured by Lowpower and can generate an output voltage of 2.5V with a minimum range of 1.8-6V. The LP3981-25B5F features fast transient response, low operating current of 6µA (typically), low dropout voltage (300mV typ.) and high PSRR. The LP3981-25B5F features short circuit protection and operation temperature -40 to +85 degC making it suitable for applications needing design flexibility. It is a great choice for use in portable electronic devices where low power consumption, efficiency and a small footprint are desired.
