The AS1367 LDO provides a solution to variable duty cycle load issues that many customers now experience,” said Bruce Ulrich, Marketing Director Consumer & Communications at austriamicrosystems. “In portable battery powered equipment, as applications are switched on and off intermittently, load current variations can become extreme. austriamicrosystems’ AS1367 LDO adapts to either heavy or light load situations maintaining an excellent overall performance. With prices at $0.35 for 1K* pcs the AS1367 is a fine addition to our new ‘Performance without the Premium’ range of LDO’s.”
The AS1367 LDO is a precise, low noise, high speed, low dropout regulator with adaptive operation. Features included are high ripple rejection and low dropout voltage, a reference voltage source, an error amplifier and a current limiter. The AS1367 LDO provides high speed operation, low power consumption and high efficiency by automatically switching between a light load and a heavy load mode depending upon the output current level.
A Bypass Pin is included to reduce noise. The device features an integrated short-circuit and over current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying. The AS1367 LDO is available in an 8-pin TDFN 2×2 package.
