XC6217 Series
ETR03022_016
200mA High Speed "Green Operation" LDO Voltage Regulators
■GENERAL DESCRIPTION
☆GreenOperation Compatible
The XC6217 series are precise, low noise, high speed, low dropout regulators with green operation (GO) function. They are
fabricated using Torex’s CMOS process. Performance features of the series include high ripple rejection and low dropout voltage,
and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit.
GO provides high speed operation, low power consumption and high efficiencies by automatically switching between a high
speed mode (HS) and a power save mode (PS) depending upon the load current level. The switching point of the GO to the
output current is being fixed inside the IC. When only high-speed operation is required, it can be fixed by inputting a high level
signal to the GO pin, thus providing operating conditions with the most suitable level of supply current for the application.
The CE function enables the output to be turned off resulting in greatly reduced power consumption. In this state, with the XC6217
series B/D Type, the IC turns on the internal switch located between the VOUT and VSS pins. This short enables the electric charge
at the output capacitor (CL) to be discharged via the internal auto-discharge resistance, and as a result the VOUT pin quickly
returns to the VSS level. The series' output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors.
Output voltage is selectable in 0.05V increments within a range of 0.80V~4.00V, using laser trimming technologies.
The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin.
