CMOS Low Iq LDO

NCP699 150 mA CMOS Low Iq LDO with Enable in TSOP−5 The NCP699 series of fixed output LDO’s are designed for handheld communication equipment and portable battery powered applications which require low quiescent. The NCP699 series features a very low ground current of 40 mA, independent of load current. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, internal resistors for setting output voltage, current limit, and temperature limit protection circuits. The NCP699 has been designed to be used with low cost capacitors. The device is housed in the micro−miniature TSOP−5 surface mount package. Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, 3.3, and 5.0 V. Other voltages are available in 100 mV steps.

Output Voltage vs. Input Voltage http://onsemi.com 5 NCP699 DEFINITIONS Load Regulation Line Regulation The change in output voltage for a change in output current at a constant temperature. Dropout Voltage The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 3.0% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Maximum Power Dissipation The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected. Line Transient Response Typical over and undershoot response when input voltage is excited with a given slope. Thermal Protection The maximum total dissipation for which the regulator will operate within its specifications. Quiescent and Ground Current The quiescent current is the current which flows through the ground when the LDO operates without a load on its output: internal IC operation, bias, etc. When the LDO becomes loaded, this term is called the Ground current. It is actually the difference between the input current (measured through the LDO input pin) and the output current. Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated at typically 160°C, the regulator
