High speed, Low dropout, ±1% High output accuracy with On/Off circuit CMOS Voltage Regulator

VRH Series

GENERAL DESCRIPTIONS

The VRH series are positive voltage regulators with high speed, low voltage dropout and high accuracy output achieved by low current consumption. The output voltage is guaranteed within ±1% within the given temperature range by Vref controlling the temperature characteristic. It corresponds to the low ESR capacitor as an output stabilization capacitor. The charged ESR capacitor can be discharged with an internal switch by making the EN=VSS, as a result the VOUT quickly returns to the VSS level. To make the current capacity of the output transistor not exceeded, the over-current protection circuit is built in.

DESCRIPTION OF OPERATION

General operation In reference to following block diagram of the VRH series ;

By the error amplifier, the reference voltage (VREF) is compared with VFEEDBACK which is divided by feedback resistors R1 and R2. It supplies the output transistor (see note *1) to keep a stabilized output voltage against with any fluctuation of input voltage by negative feedback system. Note *1)

EN terminal (shutdown function) & CL auto-discharge The VRH series can be shutdown through EN terminal. The P-channel MOSFET is turned off and operation of all internal circuits stops to reduce the current consumption when the signal of EN terminal is set to the shutdown level. In shutdown mode, the VRH series enables the electric charge at the CL to be discharged via the auto-discharge resistance (RDIS ; 160Ω), and the VOUT terminal can be rapidly returned to the VSS level as a result.

Output capacitor (CL) For phase compensation, an output capacitor (CL) is required to connected between VOUT terminal and VSS terminal as close as possible. A ceramic capacitor with capacitance value of at least 1.0µF is recommended. Of course, the suitable capacitance value should be different by the condition of each application. In addition, an input capacitor (CIN) with capacitance value of at least 1.0µF is also recommended between VIN terminal and VSS terminal for stable input power.

Over current protection and short circuit protection

Built-in over current protection circuit performs circuit protection from over current as a current limiter. When the load current reaches the limit level, the output voltage drops and output current also decreases accordingly. A current of typ. 40mA will flow when output terminal is shorted.

The VRH series has P-channel MOSFET which is connected to the VOUT terminal as the output transistor. To prevent the VRH series from being damaged due to inverse current from VOUT terminal to VIN terminal through a parasitic diode, VOUT should not be exceeded VIN+0.3V.
