Application
The IC regulates an input voltage VI in the range of 5.5 V < VI < 40 V to a nominal output
voltage of VQ = 5.0 V. A reset signal is generated for an output voltage of VQ < VRT. The
reset delay can be set with an external capacitor. The device has two logic inputs. A
voltage of VE2 > 4.0 V given to the E2-pin (e.g. by ignition) turns the device on.
Depending on the voltage on pin E6 the IC may be hold in active-state even if VE2 goes
to low level. This makes it simple to implement a self-holding circuit without external
components. When the device is turned off, the output voltage drops to 0 V and current
consumption tends towards 0 μA.
Design Notes for External Components
The input capacitor CI is necessary for compensation of line influences. The resonant
circuit consisting of lead inductance and input capacitance can be damped by a resistor
of approx. 1 Ω in series with CI. The output capacitor is necessary for the stability of the
regulating circuit. Stability is guaranteed at values of ≥ 22 μF and an ESR of ≤ 3 Ω within
the operating temperature range.
Circuit Description
The control amplifier compares a reference voltage, which is kept highly accurate by
resistance adjustment, to a voltage that is proportional to the output voltage and drives
the base of the series transistor via a buffer. Saturation control as a function of the load
current prevents any over-saturating of the power element.
The reset output RO is in high-state if the voltage on the delay capacitor CD is greater or
equal VUD. The delay capacitance CD is charged with the current ID for output voltages
greater than the reset threshold VRT. If the output voltage gets lower than VRT a fast
discharge of the delay capacitor CD sets in and as soon as VCD gets lower than VLD the
reset output RO is set to low-level (see Figure 5). The reset delay can be set within wide
range by dimensioning the capacitance of the external capacitor.
