Providing power-on reset delay for microprocessor power-up sequencing, the MIC5249 low dropout (LDO) regulator can deliver up to 300 mA and includes a user-programmable power-on reset delay function. The reset pin alerts the processor when the output of the LDO has reached and settled on the programmed value, allowing the processor to power-up gradually. The device offers fixed output voltages of 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V and 3V and stability is achieved with a common ceramic output capacitor. Other features include a noise bypass, a transient response time of 10 µs, a logic-enable input, current limiting, and thermal shutdown. Operating temperature range is from -40°C to 125°C. Typical applications include cell phones and portable computers. Available in a MSOP-8 package, the new LDO has a starting price of $0.90 each/1,000 with delivery from stock to eight weeks ARO.
