as the temperature falls, and excessive ESR is the most
likely cause of trouble at temperatures below 0°C.
Sanyo OS-CON series through-hole and surface-mount
tantalum capacitors exhibit low ESR at temperatures
below 0°C. Refer to Table 2 for recommended capaci-
tor values and suggested capacitor suppliers.
Other Components
The catch diode should be a Schottky or high-speed
silicon rectifier with a peak current rating of about 1A
for full-load (750mA) operation. The 1N5817 is a good
choice. The 330pF outer-loop compensation capacitor
provides the widest input voltage range and best tran-
sient characteristics. For low-current applications, the
510k
resistor may be omitted (see the Maximum
Output Current vs. Supply Voltage, R1 Removed graph
in the Typical Operating Characteristics).
Printed Circ uit Layouts
A good layout is essential for clean, stable operation.
The layouts and component placement diagrams given
in Figures 4-7 have been successfully tested over a
wide range of operating conditions.
The 1μF bypass
capacitor (C2) must be positioned as close to the V+
