LDOs save power in many ways
LDO regulators are compatible with low-ESR ceramic capacitors, which give added output stability, and include built-in overcurrent protection and thermal shutdown circuits.
Step-up convertors raise voltages efficiently
The XC9128/29 series from Torex deliver efficiencies up to 93% over the entire load range, and can supply 500mA to a 3.3V load from a 1.8V battery supply.
The XC2163 and XC2164 are CMOS low power, tristate-output ICs comprising a built-in crystal oscillator and a divider circuit in a compact mini-mold SOT-26 package.
The XC2163 has a standard oscillation frequency range of 20 to 125MHz, but it can also be used in buffer applications up to 160MHz.
The range of the XC2164 is a wider 4 to 125MHz.
The XC2164 is also available in die (chip) form for space critical applications.
For both devices, output is selectable from f0/1, f0/2, f0/4 and f0/8.
With oscillation capacitors and a feedback resistor built-in, it is possible to configure a stable third overtone oscillator using only a single external crystal oscillator.
Both devices are also available as external oscillation capacitor and feedback resistor versions, which make oscillation frequency control possible.
Also, packaged in a space-saving SOT-26 package, the XC2173 series additionally features a built-in clock multiplier PLL circuit with an operating oscillation frequency range of 10 to 25MHz.
As well as offering divider ratios of f0/2, f0/4 and f0/8, the connection of an external clock also gives designers multiplier ratios of fx5, fx6, fx7 and fx8.
Operating voltage is from 3.3 to 5.0V +/-10%.
In stand-by mode through the CE pin power consumption is reduced to a minimum of 1mA.
Continuous total power dissipation is 250mW.
This rugged series of oscillators is designed to operate over a temperature range of -30 to +80C.
