The FAN25800 is a linear low-dropout regulator with a high PSRR (85 dB at 100 Hz) and low output noise (typically 8 µVRMS over a 10 Hz to 100 kHz bandwidth). The LDO can provide up to 250 mA of output current for 2.8 V output and up to 500 mA of output current for 3.3 V output.The enable control pin can be used to shut down the device and disconnect the output load from the input. During shutdown, the supply current drops below 1 µA.The FAN25800 is designed to be stable with space-saving ceramic capacitors as small as 0201 case size. The FAN25800 is available in a 4-bump, 0.35 mm pitch, WLCSP package.

The FAN302HL_F117 advanced PWM controller significantly simplifies isolated power supply design that requires CC regulation of the output. The output current is precisely estimated with information in the primary side of the transformer and controlled with an internal compensation circuit. This removes the output current sensing loss and eliminates all external Control Circuitry (CC). The Green-Mode function, with an extremely low operating current (200µA) in Burst Mode, maximizes the light-load efficiency, enabling conformance to worldwide Standby Mode efficiency guidelines.Integrated protections include two-level pulse-by-pulse current limit, Over-Voltage Protection (OVP), brownout protection, and Over-Temperature Protection (OTP).Compared with a conventional approach using an external control circuit in the secondary side for CC regulation, the FAN302HL_F117 can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability.

The FAN3100 2 A gate driver is designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications by providing high peak current pulses during the short switching intervals. The driver is available with either TTL (FAN3100T) or CMOS (FAN3100C) input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output low until the supply voltage is within the operating range. The FAN3100 delivers fast MOSFET switching performance, which helps maximize efficiency in high-frequency power converter designs.FAN3100 drivers incorporate MillerDrive™ architecture for the final output stage. This bipolar-MOSFET combination provides high peak current during the Miller plateau stage of the MOSFET turn-on / turn-off process to minimize switching loss, while providing rail-to-rail voltage swing and reverse current capability.The FAN3100 also offers dual inputs that can be configured to operate in non-inverting or inverting mode and allow implementation of an enable function. If one or both inputs are left unconnected, internal resistors bias the inputs such that the output is pulled low to hold the power MOSFET off.The FAN3100 is available in a lead-free finish 2x2mm 6-lead Molded Leadless Package (MLP), for smallest size with excellent thermal performance, or industry-standard 5-pin SOT23.

The FAN3121 and FAN3122 MOSFET drivers are designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peakcurrent pulses. The drivers are available with either TTL input thresholds (FAN312xT) or VDD-proportional CMOS input thresholds (FAN312xC). Internal circuitry providesan under-voltage lockout function by holding the output low until the supply voltage is within the operating range.FAN312x drivers incorporate the MillerDrive™ architecture for the final output stage. This bipolar /MOSFET combination provides the highest peak currentduring the Miller plateau stage of the MOSFET turn-on / turn-off process.The FAN3121 and FAN3122 drivers implement an enable function on pin 3 (EN), previously unused in the industry-standard pin-out. The pin is internally pulled upto VDD for active HIGH logic and can be left open for standard operation.The commercial FAN3121/22 is available in a 3x3 mm 8-lead thermally-enhanced MLP package or an 8-lead SOIC package. The AEC-Q100 automotive-qualified versions are available in the 8-lead SOIC package.
