LDO from Diodes Incorporated Boosts Drive Capability
Diodes Incorporated has introduced a pair of ultra low dropout (LDO) linear regulators, capable of delivering a continuous 3.0A output for a dropout voltage of just 0.23mV. With maximum input voltages of 3.65V and 5.5V, respectively, the AP7175 and AP7176B provide an adjustable output voltage suitable for high-efficiency systems in a wide range of products including notebooks, PCs and set-top boxes.To m
The AP7175 and AP7176B also integrate a soft-start function that reduces in-rush current during the start-up period, which is typically 0.6ms. In addition, the LDOs’ on-board current limit, short-circuit and thermal shutdown protection functions ensure that connected loads are fully protected against any possible current excesses.
Both LDOs are provided in the reduced thermal impedance, industry-standard SO-8EP and smaller form factor MSOP-8EP exposed pad packages. These packages reduce the junction-to-case temperature differential, enabling the devices to deliver high load currents over their whole -40ºC to +85ºC ambient temperature range. The AP7175 and AP7176B are priced at $0.15 USD each in 1k quantities.
