Reading time ( words)
The S-8321, S-8322, S-8323, S-8324, S-8327 and S-8328 Series CMOS switching regulator ICs measure 2.8 x 2.9 x 1.3 mm in SOT-23 packaging. They have an internal oscillation frequency of 30 to 100 kHz, with a high oscillation frequency of 250 kHz available. The regulators are available with an internal or external switching transistor with either pulse frequency modulation (PFM), pulse width modulation (PWM), or both PFM and PWM controls.
