1 XC1 Series ETR9_7 Dual LDO Regulators, Low ESR Cap. Compatible GENERAL DESCRIPTION The XC1 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance features of the series includes low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. The XC1 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators internally. The XC1 s current limiters' foldback circuit also operates as a short protect for the output current limiter. The output voltage for each regulator is set independently by laser trimming. Voltages are selectable in.5v steps within a range of.8v to 5.V. The XC1 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The XC1 series is available in the SOT-W or USP-B, USP-C chip-scale package.

6 XC1 Series OPERATIONAL EXPLANATION < Control> The voltage divided by resistors R1 & R is compared with the internal reference voltage by the error amplifier. The P-channel MOSFETs, which are connected to the VOUT1 and VOUT pins, are then driven by the subsequent output signal. The output voltages at the VOUT1 and VOUT pins are controlled and stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal. EN1 ON/OFF Control - Error Amp1 + Current Limit VOUT1 VR1 each circuit R11 R1 VIN VSS VR each circuit Voltage Reference - Error Amp + Current Limit R1 VOUT EN ON/OFF Control R <Low ESR Capacitors> With the XC1 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that output capacitors (CL1, CL) is connected as close as possible to the output pins (VOUT1 and VOUT) and the VSS pin. Please use an output capacitor with a capacitance value of at least 1μF. Also, please connect an input capacitor (CIN) of 1μF between the VIN pin and the VSS pin in order to ensure a stable power input. <Current Limiter, Short-Circuit Protection> The XC1 series includes a combination of a fixed current limiter circuit & a foldback circuit which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about ma flows. <EN Pins> The IC's internal circuitry can be shutdown via the signal from the EN1 and EN pins with the XC1 series. In shutdown mode, output at the VOUT1 and VOUT pins will be pulled down to the VSS level via R11 & R1 and R1 & R. The operational logic of the IC's EN1 and EN pins are selectable (please refer to the selection guide). Note that as the standard XC1FF type's regulator 1 and are both ' High Active/No Pull Down', operations will become unstable with the EN1 or EN pins open. Although the EN1 and EN pins are equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the EN1 and EN pins input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN1 and EN pins. If this IC is used with the correct specifications for the EN1 and EN pins, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry. NOTES ON USE 1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded.. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance low between VIN and VSS wiring in particular.. Please wire the input capacitor (CIN) and the output capacitors (CL1, CL) as close to the IC as possible. /
