MAX667
put-capacitor ESR and this series resistance should, at
minimum, meet the requirements shown in Figure 4.
An upper limit to the output-capacitor ESR is important
only if step changes to the load are anticipated. Higher
ESR results in higher-amplitude output-voltage tran-
sients when the output current is varied. A Sanyo
OS-CON capacitor, whose ESR is nearly flat over tem-
perature (and is low to begin with), in series with the
appropriate resistor ensures the best load-transient
performance. A less expensive alternative is to use a
tantalum capacitor in series with the resistor.
In most cases, inexpensive aluminum-electrolytic
capacitors work well with the MAX667 over their entire
temperature range, having sufficient ESR to ensure sta-
bility without the need for a series resistor. The ESR of
aluminum electrolytics rises, often dramatically, as tem-
perature decreases. For surface-mount applications,
certain tantalum capacitors have sufficient ESR; an
example is the TAJB106K016 chip capacitor made by
AVX (phone: (803) 448-9411, fax: (803) 448-1943).
Battery Drain
The MAX667 uses a PNP output transistor. When the
input voltage falls below the desired output voltage, the
