XC6701 Series
ETR0334-008a
28V Operation High Speed Voltage Regulators with Stand-by Function
■GENERAL DESCRIPTION
The XC6701 series are positive voltage regulator ICs manufactured using CMOS process with 28V of operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal protection circuit and a phase compensation circuit plus a driver transistor. The output voltage is selectable in 0.1V increments within the range of 1.8V to 18V which fixed by laser trimming technologies. The output stabilization capacitor (C The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption. Packages are selectable depending on the applications from SOT-25, SOT-89, SOT-89-5, USP-6C, SOT-223, and TO-252.

■ OPERATIONAL EXPLANATION
<Output Voltage Control>
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected to the V voltage at the V circuit and thermal protection circuit operate in relation to the level of output current and heat generation. Further, the IC’s internal circuitry can be shutdown via the CE pin’s signal.
<Short-Circuit Protection>
The XC6701 series includes a current fold-back circuit as a short circuit protection. When the load current reaches the current limit level, the current fold-back circuit operates and output voltage drops. The output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows.
<CE Pin>
The IC’s internal circuitry can be shutdown via the signal from the CE pin with the XC6701B series. In shutdown mode, output at the V become unstable with the CE pin open. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC’s internal circuitry if a medium voltage is applied.
<Thermal Shutdown>
When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the thermal protection circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release voltage.
<Minimum Operating Voltage>
For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated normally if the input voltage is less than 2.0V.
■ NOTES ON USE
1． For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be
exceeded.
2． Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on output
current. Please strengthen V
3. Phase compensation inside the IC is performed in the XC6701 series. Therefore, an abnormal oscillation does not occur even if there is no output capacitor CL. An input capacitor CIN around 0.1μF~1.0μF between the VIN pin and the V is required for input stability. Also, the output voltage fluctuation such as under shoot or over shoot, which occurs because of the load change can be controlled by placing the output capacitor C pin and VSS pin. The input capacitor (CIN) and the output capacitor (CL) should be placed to the IC as close as possible with a shorter wiring.
4. When the IC is operated with no load, the output voltage may increase in the high temperature beyond operating range.
