Micro-Power Low Voltage Supervisor

General Description The MIC2776 is a power supply supervisor which provides under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. Features include an adjustable under-voltage detector, a delay-generator, a manual reset input, and a choice of active-high, active-lo

5 V, SUPER MINIMOLD SILICON MMIC MEDIUM OUTPUT POWER AMPLIFIER

DESCRIPTION The µPC2776TB is a silicon monolithic integrated circuits designed as wideband amplifier. This amplifier has impedance near 50 Ω in HF band, so this IC suits to the system of HF to L band. This IC is packaged in super minimold package which is smaller than conventional minimold. The
