3 / 12 page © 2002 Microchip Technology Inc. DS21373B-page 3 TC1262 2.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 2-1. TABLE 2-1: PIN FUNCTION TABLE 3.0 DETAILED DESCRIPTION The TC1262 is a precision, fixed output LDO. Unlike bipolar regulators, the TC1262’s supply current does not increase with load current. In addition, VOUT remains stable and within regulation over the entire 0mA to ILOADMAX load current range (an important consideration in RTC and CMOS RAM battery back-up applications). Figure 3-1 shows a typical application circuit. FIGURE 3-1: TYPICAL APPLICATION CIRCUIT 3.1 Output Capacitor A1 µF (min) capacitor from VOUT to ground is required. The output capacitor should have an effective series resistance greater than 0.1 Ω and less than 5Ω,and a resonant frequency above 1MHz. A 1 µF capacitor should be connected from VIN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30°C, solid tantalums are recommended for applications operating below -25°C.) When operating from sources other than batteries, supply-noise rejection and transient response canbeimprovedbyincreasingthe valueof the input and output capacitors and employing passive filtering techniques.
