TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR5SB15~TCR5SB5 2 ma CMOS Low-Dropout Regulators (Point Regulators) TCR5SB15~TCR5SB5 The TCR5SB15 to TCR5SB5 are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage and low quiescent bias current. The TCR5SB15 to TCR5SB5 can be enabled and disabled via the CONTROL pin. These voltage regulators are available in fixed output voltages between 1.5 V and 5. V in.1-v steps and capable of driving up to 2 ma. They feature overcurrent protection. The TCR5SB15 to TCR5SB5 are offered in the compact SMV (SOT23-5) (SC-74A) and allow the use of small ceramic input and output capacitors. Thus, these devices are ideal for portable applications that require high-density board assembly such as cellular phones. Weight:.14 g (typ.) Features Low quiescent bias current ( I B = 4 μa (typ.) at I OUT = ma ) Low stand-by current ( I B(OFF) =.1 μa (typ.) @ Stand-by mode ) Low-dropout voltage ( V IN - V OUT = 85 mv (typ.) at TCR5SB3, I OUT = 5 ma ) High current output ( I OUT = 2 ma (max) ) High ripple rejection ( R.R = 8 db (typ) @ I OUT = 1 ma, f =1kHz ) Low output noise voltage ( V NO = 3 μv rms (typ.) @ TCR5SB3, I OUT = 1 ma, 1 Hz f 1 khz ) Control voltage can be allowed from -.3 to 6 V regardless of V IN voltage.

3. Ripple Rejection TCR5SB15~TCR5SB5 TCR5SBxx series are designed for superior ripple rejection characteristic. Even an output changes with steep resistance rate of the power supply voltage, characteristic of Input Transient Response, the ripple rejection shows an extremely superior characteristics.

However, because of the type of the capacitors, there might be unexpected thermal features. Please consider application condition for selecting capacitors. And Toshiba recommend the ESR of ceramic capacitor is under 1 Ω. Mounting The long distance between IC and output capacitor might affect phase assurance by impedance in wire and inductor. For stable power supply, output capacitor need to mount near IC as much as possible. Also GND pattern need to be large and make the wire impedance small as possible. Permissible Loss Please have enough design patterns for expected maximum permissible loss. And under consideration of surrounding temperature, input voltage, and output current etc, we recommend proper dissipation ratings for maximum permissible loss; in general maximum dissipation rating is 7 to 8 percent. Overcurrent Protection Circuit Overcurrent protection circuit is designed in these products, but this does not assure for the suppression of uprising device operation. If output pins and GND pins are shorted out, these products might be break down. In use of these products, please read through and understand dissipation idea for absolute maximum ratings from the above mention or our Semiconductor Reliability Handbook. Then use these products under absolute maximum ratings in any condition. Furthermore, Toshiba recommend inserting failsafe system into the design. 7 28-1-16
