| CM2860/CM2861 600mA CMOS LDO GENERAL DESCRIPTION The CM2860/2861 family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30A typ.), low dropout voltage, and high output voltage accuracy. Built-in low on-resistance transistor provides low dropout voltage and large output current. A 2.2F or greater can be used as an output capacitor. The SOT-89 and SOT-223 packages are attractive for "Pocket" and "Hand Held" applications. These robust devices are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back.

The P-channel pass transistor receives data from the error amplifier, over-current shutdown, short output protection, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal shutdown circuits become active when the junction temperature exceeds 150, or the current exceeds 600mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 120. The CM2860/CM2861 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. The CM2860/2861 also incorporates current fold-back to reduce power dissipation when the output is short-circuited. This feature becomes active when the output drops below 0.8V, and reduces the current flow by 65%. Full current is restored when the voltage exceeds 0.8V. EXTERNAL CAPACITOR The CM2860/CM2861 is stable with an output capacitor to ground of 2.2F or greater. It can keep stable even with higher or poor ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 0.1F to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A "quiet" ground termination is desirable. 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 5 CM2860/CM2861 600mA CMOS LDO TYPICAL ELECTRICAL CHARACTERISTICS 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 6 CM2860/CM2861 600mA CMOS LDO 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 7 CM2860/CM2861 600mA CMOS LDO PACKAGE DIMENSION SOT-89 (M89) D D1 A 1.0 E H L e e1 5 C 8 A L b b1 C D D1 H E e1 b b1 b e SOT-223 (M223) D B1 A E L1 H e e1 A 8 B B1 D E e e1 H L L1 B B 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation L Page 8 CM2860/CM2861 600mA CMOS LDO NUMBERING SCHEME Ordering Number: CM2860XYZ/CM2861XYZ (note1) Ordering Number: CM2860GXYZ/CM2861GXYZ (note2) note1: CM2860/CM2861: 600mA CMOS LDO X : Suffix for voltage output (note 3) Y : Suffix for Temperature Range (note 4) Z : Suffix for Package Type (note 5) note2: CM2860/CM2861: 600mA CMOS LDO G : Suffix for Pb Free Product X : Suffix for voltage output (note 3) Y : Suffix for Temperature Range (note 4) Z : Suffix for Package Type (note 5) note 3: see CMOS LDO Voltage Suffix Table note 4: Y= I : -40~+85 (only I grade support for all CMOS LDOs) note 5: Z is single alphabet with or without digits M223 : SOT-223 (TR only) M89 : SOT-89 (TR only) CMOS LDO Voltage Suffix Table Output Voltage 1.5V 1.6V 1.7V 1.8V 1.9V 2.0V 2.1V 2.2V 2.3V 2.4V 2.5V 2.6V 2.7V 2.8V 2.9V Suffix A B C D E F G H I J K L M N O Output Voltage 3.0V 3.1V 3.2V 3.3V 3.4V 3.5V 3.6V 3.7V 3.8V 3.9V 4.0V Suffix P Q R S T U V W X Y Z 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 9 CM2860/CM2861 600mA CMOS LDO IMPORTANT NOTICE Champion Microelectronic Corporation (CMC) reserves the right to make changes to its products or to discontinue any integrated circuit product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current.
