Dual 1A Adjustable/Fixed Low Dropout Linear Regulators

Description The FAN1537 provides 2 output voltages: 3.3V, and either adjustable or 2.5V or 1.8V fixed with 1.0A each output current capability. These devices have been optimized for low voltage where transient response and minimum input voltage are critical. Features • Low dropout voltage • Lo

700mA SmartLDOTM

DESCRIPTION The SC1537 is designed to maintain a glitch-free 3.3V output when at least one of two inputs, 5V (VIN) and 3.3V (VAUX), is present. Whenever VIN exceeds a predetermined threshold value, the internal 3.3V linear regulator is enabled, and DR is pulled high. FEATURES • Glitch-free tra
