XC6702 Series
36V input, 300mA low supply current, high speed voltage regulators
ETR03074-001
■GENERAL DESCRIPTION
The XC6702 series are CMOS high-speed voltage regulator ICs with a 36 V input and low supply current.
Internal circuitry includes a reference voltage supply, error amplifier, driver transistor, over-current protection circuit, overheat
protection circuit, soft start circuit, and phase compensation circuit.
The output voltage is fixed internally by laser trimming, and product selections from 1.8V to 18.0V are available.
The over-current protection circuit and overheat protection circuit are built-in, and when the output current reaches the current
limit or the junction temperature reaches the temperature limit, the corresponding circuit activates.
The soft start circuit limits the rush current that flows from VIN to VOUT when the IC starts, enabling a stable startup sequence.
The IC is put in the standby state by inputting L level into the CE pin, and the supply current is reduced to 0.1μA.
A low-ESR capacitor such as a ceramic capacitor can also be used for CL.

■OPERATIONAL EXPLANATION (Continued)
＜Soft start＞
The XC6702 series limits the rush current (IRUSH) that suddenly flows from VIN to VOUT to charge the
output capacitor (CL) when the IC starts, and is also able to limit fluctuations of VIN due to IRUSH. The
soft start time(tss) is optimized internally(370μs TYP.). The soft start time(tss) is defined as the VOUT
reaches 90% of VOUT(T) from the time when CE H threshold is input to the CE pin.

＜Low ESR capacitor support＞
An internal phase compensation circuit is incorporated in the XC6702 series to enable a stable output
voltage to be obtained even when a low ESR capacitor is used. To stabilize the effect of the phase
compensation circuit, always connect the output capacitor (CL) in direct proximity to the VOUT pin and
VSS pin. In addition, to stabilize the input power, connect the input capacitor (CIN) in direct proximity to
the VIN pin and VSS pin. Refer to Table 1 for the recommended capacitance values to be connected.
Take particular care in selecting the capacitors for CIN and CL, as the bias dependence of the capacitor,
the effect of capacitance loss due to temperature characteristics and other factors, and the effects of
ESR may prevent stable phase compensation. Table 1 shows recommended capacitance values (MIN)
for the actual bias and temperature conditions used for the capacitor. Select capacitances that satisfy
Table 1 in all environments in which the product is to be used.
