The LM2750 is a switched-capacitor doubler that produces a low-noise, well regulated, 5.0V output. It can supply up to 120mA of output current over a 2.9V to 5.6V input range, as well as up to 40mA of output current when the input voltage is as low as 2.7V. The LM2750 has been placed in National's 10-pin LLP, a package with excellent thermal properties that keeps the part from overheating under almost all rated operating conditions A perfect fit for space-constrained, battery-powered applications, the LM2750 requires only 3 external components: one input capacitor, one output capacitor, and one flying capacitor. Small, inexpensive ceramic capacitors are recommended for use. These capacitors, in conjunction with the 1.7MHz fixed switching frequency of the LM2750, yield low output voltage ripple, beneficial for systems requiring a lownoise 5V supply. Pre-regulation minimizes input current ripple, reducing input noise to negligible levels.
